if the perimeter of the triangle is 19 meters what is the length of the longest side
HELP THIS IS DUE TODAY
Answer:
17+1+1
Step-by-step explanation:
Answer:
The longest side can be anything but the number of the longest side has to be less than the other 2 sides after you add them together.
example: The longest side can be 9 and the other 2 sides are 5. When you add them both together they equal 10 which is more than 9 so it would work.
crying help me please :(
Answer:
AB = 10
EF = 2
Step-by-step explanation:
to find the scale factor you have to divide the bigger scale by the smaller one which would be
(5x)/5 and 4/x
since both scale factors should be the same you can set them even to each other
(5x)/5=4/x
solve for x
(5x)/5=4/x
x=4/x
x^2=4
x=2

Answer:
Negative 7/40 or - 7/40
Step-by-step explanation:
Answer: -7/40
Step-by-step explanation:
first multiply the two negatives so it becomes (2-|-1/4+2 x 3/5|) /(-6)
then that becomes (2- | -1/4 + 6/5 | ) /(-6)
the sum of those two fractions become (2- | 19/20|) /(-6)
(2-19/20)/(-6)
2 - 19/20 /-6
21/20 /-6
multiple both by a negative so that become -21/20 /6
multiply the 6 with the recirocal so it becomes 1/6
-21/20 and 1/6 turn into -7/20 and 1/2 by canceling out with the greatest common factor of 3
now multiply both and u get -7/40
question
how would you solve this problem
the ratio of *name*'s age to his brother's is 2:3. In ten years, the ratio would be 4:5. How old is *name* and his brother now and in 10 years?
also how would you solve it if the ratio changed to something different, ex: 1:3 to 3:5 in 10 years
Answer:
*name* is 10 years old now and brother is 15 years now
In 10 years they would be 20 and 25 respectively
Step-by-step explanation:
Let x = *name*'s age now
let y = brother's age now
The first relationship is that the ratio of their ages now is 2:3 or, in fraction form 2/3
That means x/y = 2/3
Cross multiply => 3x = 2y =>
3x - 2y = 0 [1]
10 years from now x would become x + 10 years, y would become y + 10 years and the new ratio is 4/5
So (x + 10)/(y+10 = 4/5
Cross-multiply
5(x + 10) = 4(y + 10)
5x + 50 = 4y + 40
Subtract 4y from both sides
5x + 50 -4y = 40
and subtract 50 from both sides:
5x - 4y = 40 - 50
5x -4y = -10 [2]
Eliminate y terms by multiplying [1] by 2 and subtracting [1] from that
[1] x 2
=> 2(3x - 2y) = 2 x 0
=> 6x - 4y = 0 [3]
[3] - [2]
6x - 4y - (5x -4y) = 0 - (-10)
6x - 4y -5x + 4y = 10
x = 10
Using equation [1] we get
x/y = 2/3
=> 10/y = 2/3
10 x 3/2 = y
5 x 3 = y
y = 15
So their ages are 10 and 15 now.
In 10 years they would be 20 and 25
If the ratios change we would have a different set of equations to solve for
For example if the current ratio is 1/3
Then we would get x/y = 1/3
or 3x - y = 0 [4]
and if 10 years from now the ratio is 3/5 then
(x + 10)/(y + 10) = 3/5
=> 5(x+10) = 3(y + 10)
=> 5x + 50 = 3y + 30
=> 5x - 3y = -20 [5]
And we would solve these equations to get x and y in a similar mannter
FYI the answers would be
x = 5, y = 15

Answer:
Loren's work is not correct because you are originally dividing by 61.4. In the division problem, they moved the decimal point to the right and did the same to the problem inside of the division symbol to make it easier. After you would finish doing all the division, you would count the amount of spaces behind the decimal point and put the decimal point that many spaces in the answer. Loren forgot to count the decimal point that you moved right at the beginning. To summarize, Loren forgot the decimal point you moved at the beginning and Maddie is correct.

Answer:
a = 8
Step-by-step explanation:
Write the equation:
7/a = 35/40
Divide:
7/a = 35/40
7/a = 35 ÷ 40
7/a = 0.875 (convert back to a fraction)
7/a = 7/8
Multiply:
8a • 7/a = 7/8 • 8a
8 • 7 = a • 7
56 = 7a
Divide to get answer:
56/7 = 7a/7
8 = a
a = 8

The data in this table represents a linear function.
What is the slope of this line?
Answer: slope = 1/2
Step-by-step explanation:
(y2 - y1) / (x2 - x1) = m
(4 - 3) / (6 - 4) = m
m = 1/2
slope = 1/2
In ΔJKL, m∠J = 78° and m∠L = 90°. Determine the measure of the exterior angle to ∠K.
168°
102°
57°
12°
Answer:
168°
Step-by-step explanation:
The sum of two interior angles in a triangle is equal to an exterior angle that is supplementary to the third interior angle, which is k, in this case.
m∠J = 78 and m∠L = 90° so the measure of exterior angle to ∠K:
78 + 90 = 168°

the answer is c (-1)
Step-by-step explanation:
slope is y^2-y^1 over x^2-x^1. so for x, -1-(-5) equals 4. so x is -1
which graph correctly shows the solution to the inequality 7x-3/9 ≥ 8-2x
(Have to make own graph)
Answer:
Simplify:
7x - 3 ≥ (8 - 2x) * 9
7x - 3 ≥ 72 - 18x
7x + 18x ≥ 72 + 3
25x ≥ 75
x ≥ 75 / 25
x ≥ 3

How does the Distributive Property help when combining like terms to solve the equation 4x + 6x = 30?
Answer: it helps by making the question 10 times easier
Step-by-step explanation: because 4 and 6 both have the variable X they are like terms and can be added to each other unlike 30 it doesn’t have a variable meaning 4x or 6x cannot combine with 30 because it doesn’t have the variable X. Moving on 4x+6x is 10x as you add the number but X stays the same and so 10x=30 so you divided both sides by 10 because inverse operations and you get x=3 then after you import that into the question 4(3)+6(3)=30 which is the same as 12+18=30 which is true 30=30
