Answer: 20× + 10 < 90
Step-by-step explanation:
Blake will have to mow at least 7 lawns to have at least $90 saved.
The inequality is: 20 + 10x ≥ 90
The solution is: x ≥ 7
What is inequality?Inequality is a mathematical statement that compares two values, expressing that one value is less than, greater than, less than or equal to, greater than or equal to, or not equal to another value.
Inequalities are commonly represented using symbols such as "<" (less than), ">" (greater than), "≤" (less than or equal to), "≥" (greater than or equal to), or "≠" (not equal to).
Let's assume Blake has to mow x lawns to have at least $90 saved.
Since he earns $10 for every lawn he mows, the amount he will earn by mowing x lawns is 10x.
Adding his initial savings of $20 to the amount he will earn from mowing lawns gives us the following inequality:
20 + 10x ≥ 90
Subtracting 20 from both sides:
10x ≥ 70
Dividing both sides by 10:
x ≥ 7
Therefore, Blake will have to mow at least 7 lawns to have at least $90 saved.
The inequality is: 20 + 10x ≥ 90
The solution is: x ≥ 7

Rendering math...While solving an equation, Wayra made some mistakes. Her solution is given below. Please help her to identify the step in which there is a mistake and also the right solution. Step 1: 13(z+6) = 4(z-3)-5z Step 2: 13z+19 = 4z-12-5z Step 3: 13z+19 = z-12 Step 4: 13z+z = -19-12 Step 5: 14z =-31 Step 6: z =-3114 Wayra has made a mistake at?
Answer:
According to the calculation, Wayra mage a mistahe in step 2 where she added 13 and 6 together instead of multiplying to get 78.
She also make a mistake in step 2 where he subtracted 5z from 4z to get z instead of -z
Step-by-step explanation:
Given the equation solved by Wayra expressed as;
Step 1: 13(z+6) = 4(z-3)-5z
She is find the value of z from the equation;
Step 2: Open the parenthesis using the distributive property;
13(z+6) = 4(z-3)-5z
13z + 13(6) = 4z - 4(3) - 5z
13z + 78 = 4z - 12 - 5z
Step 3: Simplify
13z + 78 = 4z - 5z - 12
13z + 78 = -z -12
Step 4: Collect the like terms;
13z + z = -12 - 78
Step 5: Simplify the result
14z = -90
Step 6: Divide both sides by 14
14z/14 = -90/14
z = 6.428
According to the calculation, Wayra mage a mistahe in step 2 where she added 13 and 6 together instead of multiplying to get 78.
She also make a mistake in step 2 where he subtracted 5z from 4z to get z instead of -z

Eloise bought 3 boxes of crackers to share with her friends over the weekend. They ate 1/2 box of crackers on Saturday and 2/3 box of crackers on Sunday.
How many boxes of crackers were left over?
1 3/5 boxes
1 5/6 boxes
2 3/5 boxes
2 5/6 boxes
Answer:
C.) 1 5/b boxes
Number of boxes left over
= 3 - 1/2 - 2/3
Convert each fraction to one in terms of the LCM:
= 18/6 - 3/6 - 4/6
= 11/6
= 1 5/6 boxes.
The solution is Option B.
The number of boxes of crackers left with Eloise is 1 5/6 boxes of crackers
What is an Equation?
Equations are mathematical statements with two algebraic expressions flanking the equals (=) sign on either side.
It demonstrates the equality of the relationship between the expressions printed on the left and right sides.
Coefficients, variables, operators, constants, terms, expressions, and the equal to sign are some of the components of an equation. The "=" sign and terms on both sides must always be present when writing an equation.
Given data ,
Let the number of boxes of crackers left with Eloise be = A
Now , the total number of boxes of crackers be = 3 boxes
The number of boxes of crackers ate on Saturday = 1/2
The number of boxes of crackers ate on Sunday = 2/3
So , the equation will be
Number of boxes of crackers left with Eloise A = total number of boxes of crackers - number of boxes of crackers ate on Saturday - number of boxes of crackers ate on Sunday
Substituting the values in the equation , we get
Number of boxes of crackers left with Eloise A = 3 - 1/2 - 1/3
On simplifying the equation , we get
Number of boxes of crackers left with Eloise A = 5/2 - 2/3
Number of boxes of crackers left with Eloise A = ( 15 - 4 ) / 6
Number of boxes of crackers left with Eloise A = 11/6
Number of boxes of crackers left with Eloise A = 1 5/6 boxes
Therefore , the value of A is 1 5/6 boxes
Hence , the number of boxes left is 1 5/6 boxes of crackers

What is the y-intercept of the equation of the line that is perpendicular to the line v= x -x+ 10 and passes through the
point (15,-5)?
O y=xx-20
O y=-3x+20
Ov=3x-2
Ov=-3x+20
Answer:
[tex]y=-\frac{5}{3}x+20[/tex]
Here, m=-5/3, and b=y-intercept=20
Here, the y-intercept is: 20
Thus, option (d) is true.
Step-by-step explanation:
Given the equation
[tex]y=\frac{3}{5}x+10[/tex]
comparing the equation with the slope-intercept form
[tex]y=mx+b[/tex]
Here,
m is the slope y is the interceptso the slope of the line is 3/5.
As we know that the slope of the perpendicular line is basically the negative reciprocal of the slope of the line, so
The slope of the perpendicular line will be: -5/3
Therefore, the point-slope form of the equation of the perpendicular line that goes through (15,-5) is:
[tex]y-y_1=m\left(x-x_1\right)[/tex]
[tex]y-\left(-5\right)=\frac{-5}{3}\left(x-15\right)[/tex]
[tex]y+5=\frac{-5}{3}\left(x-15\right)[/tex]
simplifying the equation to convert it into the slope-intercept form
We know that the slope-intercept form of the line equatio is
[tex]y=mx+b[/tex]
here 'm' is the slope and 'b' is the y-intercept
[tex]y+5=\frac{-5}{3}\left(x-15\right)[/tex]
subtract 5 from both sides
[tex]y+5-5=\frac{-5}{3}\left(x-15\right)-5[/tex]
[tex]y=-\frac{5}{3}x+20[/tex]
Here, m=-5/3, and b=y-intercept=20
Here, the y-intercept is: 20
Thus, option (d) is true.

Judy is baking 5 cheesecakes. A recipe for one of the cheesecakes requires 1 1 2teaspoons of vanilla. Judy's bottle of vanilla contains 12 teaspoons of vanilla. After Judy bakes the 5 cheesecakes, how many teaspoons of vanilla will be left in the bottle?
Answer:4 1/2 Teaspoons of vanilla will be left in the bottle
Step-by-step explanation:
Step 1
Recipe for 1 cheesecake = 1 1/2 teaspoons of vanilla
Since she s making 5 cheesecakes, she will requite = 5 x 1 1/2 teaspoons
= 5 x 3/2= 15/2 = 7 1/2 teaspoons of vanilla.
Step 2
If a bottle of vanilla contains = 12 teaspoons of vanilla
After baking 5 cheesecakes which consumed = 7 1/2 teaspoons of vanilla
Teaspoons left of vanilla = Total teaspoons of vanilla-teaspoons of vanilla used for 5 cheesecakes= 12 - 7 1/2 =4 1/2
Therefore 4 1/2 Teaspoons of vanilla will be left in the bottle
Help please The actual distance between Apple Street and Pear Road is 8 miles. On a map, the distance is 3.5 inches. What proportion can you form to determine the scale on the map? 1 inch = ?
Answer:
1 in on the map = [tex]\frac{16}{7}\ miles[/tex] on the street
Step-by-step explanation:
Represent the actual distance as y and the map distance as x
So:
x = 3.5in when y = 8 miles
Required
Determine the proportion
The proportion of map measurement to actual measurement is:
[tex]x : y[/tex]
This gives:
[tex]3.5\ in : 8\ miles[/tex]
Divide by 3.5
[tex]\frac{3.5\ in}{3.5} : \frac{8\ miles}{3.5}[/tex]
[tex]1\ in: \frac{8\ miles}{3.5}[/tex]
Simplify the fraction
[tex]1\ in: \frac{8 * 2\ miles}{3.5*2}[/tex]
[tex]1\ in: \frac{16\ miles}{7}[/tex]
[tex]1\ in: \frac{16}{7}\ miles[/tex]
This means that:
1 in on the map = [tex]\frac{16}{7}\ miles[/tex] on the street
