Eric traveled to three cities on a single highway. The distance from his original location to the first city was 100 miles more than the distance from the first city to the second city. The distance from the second city to the third city was 10 miles less than the distance from the first city to the second city. If the distance from his original location to the first city and the distance from the second city to the third city were the same, what was the total distance Eric traveled?
Answer:
Well think about it, the key words there are more than and less than so if he traveled let's say from his house until the first city that's 100 miles for the first one and then they say that he traveled 10 miles less than the distance from the first city until the second city. The total distance is 280 because if you read the very last sentence it says that from the original distance from the first city is about 100 miles and then it says if the the distance from the second city to the third city was the same that means that the equation goes like this: (90*2)+100 and in order to get this correctly you must do P.E.M.D.A.S which is parenthesis, exponents, multiplying, dividing, adding and subtracting so there you go.

Who can solve these three ??
Answer:
1) x = 9
2) y = 16
3) y = -1
Step-by-step explanation:
Do PEMDAS in reverse.
For every equation, your goal is to seperate the variable (x,y, or whatever letter) by itself.
1) 2x-7 = 11
Add 7 to both sides.
2x = 18
Divide both sides by 2.
x = 9
2) [tex]\frac{3}{4}y = 12[/tex]
Divide both sides by 3/4 (which turns into multiplying by 4/3).
Left side
[tex]\frac{3}{4}x * \frac{4}{3}\\\\\frac{3}{4}x * \frac{4}{3} = \frac{3*4}{4*3}x\\1x\\x[/tex]
Right side
[tex]12*\frac{4}{3}\\\\\frac{12}{1} *\frac{4}{3}\\\\ \frac{12}{1} *\frac{4}{3} = \frac{12*4}{1*3}\\\\\frac{48}{3} \\16[/tex]
3) 9(y+3) = 18
Remember do PEMDAS in reverse.
Divide both sides by 9.
y+3 = 2
Subtract both sides by 3.
y = -1

-5x-9 is greater than or equal to -4
Answer x is less than or equal to -1
Step-by-step explanation:
-5x-9 -4
-5x-9+9 -4+9
-5x 5
-5x/-5x 5/-5
x less than or equal to -1
Answer:
x [tex]\leq[/tex] -1
Step-by-step explanation:
(-5x - 9) [tex]\geq[/tex] -4
add 9 to both sides of the equation
-5x-9 [tex]\geq[/tex] -4
+9 +9
--------------------
the -9 and +9 cancel out
-5x [tex]\geq[/tex] 5
then, divide both sides by -5 to get x
-5x [tex]\geq[/tex] 5
------ -------
-5 -5
x [tex]\leq[/tex] -1
by the way, the sign changed from [tex]\geq[/tex] to [tex]\leq[/tex] because we divided by a negative number to get x.

FINAL ROUND!! Could someone please help answer this thanks so much, please no spam, will give brainliest (homework help)
Answer:
a is less than or equal to 7
Step-by-step explanation:
This is the case because we can treat the less than or equal to sign as an equal sign. The only time it changes is when we divide by a negative, but we do not do that in this problem. First, you subtract 7 from both sides. That leaves us with a 4a on one side and a 28 on the other. Then, you divide both sides by four to get a is less than or equal to 7. I hope this helps!

Math expert please provide the product in standard form
is 3/4 and 10/15 proportional
Answer:
3/4 and 10/15 are not proportional
Step-by-step explanation:
3 is not a factor of 10 and 4 is not a factor of 15
Answer:
No
Step-by-step explanation:
3/4 is already simplified all the way, but 10/15 is not. 10/15 simplifies down to 2/3 (because 5x2=10 and 5x3=15), which is not equivalent to 3/4.
Rewrite y - 3 = -9(x - 1) in standard form.
Answer:
9x + y = 12
Step-by-step explanation:
Hi there!
We are given the equation y - 3 = -9(x-1) and we want to write it in standard form
The equation is currently in point-slope form, which is [tex]y-y_1=m(x-x_1)[/tex], where [tex](x_1 , y_1)[/tex] is a point and m is the slope. Standard form is ax + by = c, where a, b, and c are free integer coefficients
We can first convert the equation from point-slope form into slope-intercept form, which is y=mx+b, where m is the slope and b is the y intercept
We can distribute 9 to every term on the right side:
y - 3 = -9x + 9
Now add 3 to both sides
y = -9x + 12
Now the equation is in slope-intercept form (y=mx+b). To make it standard form, add 9x to both sides, to make the form ax + by = c .
9x + y = 12

Kaya started with the number 92. After multiplying by a power of 10, her number increased to 920,000. What power of 10 did Kaya multiply her original number by to get an answer of 920,000? Explain the reason for this solution
The new number has 4 zeros so the power was 4
Answer: 4
Answer:
4
Step-by-step explanation:
kaya started with 92
then multiplied it by
[tex]10 ^{x} [/tex]
[tex]92 \times {10}^{x} [/tex]
[tex]92 \times {10}^{x} = 920000[/tex]
divide both sides by the coefficient of
[tex] {10}^{x} [/tex]
[tex] {10}^{x} = \frac{920000}{92} [/tex]
[tex] {10}^{x} = 10000[/tex]
[tex] {10}^{x} = {10}^{4} [/tex]
since they both have the same numbers we can cancel the two 10
therefore:
x = 4

Solved ✔︎The length of a rectangle is 4ft longer than it’s width. If the perimeter of the rectangle is 68ft, find it’s length and width.
Answer:
Represent the length and width by L and W. Then L = W + 4.
Using the perimeter formula: P = 2L + 2W = 68 ft = 2W) + 2(W+4).
Solve for W: 68 = 2W + 2W + 8, or 4W = 60. Thus, W = 15 and L = 19.
The dimensions of the rectangle are 15 by 19 feet.
