They give you the equation: 2(5x-2)+2(3x+1)
and they give you x. x=4
just substitute and solve: 2((5•4)-2)+2((3•4)+1)=2(20-2)+2(12+1)=2(18)+2(13)=36+26=62
He had a 2021 decrease in dollars to find this you have to do 8600x23.5=202,100 and then divide it by 100. For the second part just subtract 8600 from 2021 and your answer is 6,579
To answer this question, you will need to determine how many times greater each side is using the lengths of the longest sides.
To find how many times greater 275 is than 50, divide them.
275/50 = 5.5
Triangle TUV has a perimeter that is 5.5 times longer than triangle IJK.
The perimeter of IJK is 24 + 40 + 50 or 114 units.
The perimeter of TUV would be 114 x 5.5
114 x 5.5 = 627 units
The perimeter of TUV is 627 units.
Answer:
Step-by-step explanation:
To solve for t, you have to isolate it on one side of the equation.
<h3>-17=-9+4t</h3>
<u>First, you have to switch sides.</u>
→ -9+4t=-17
<u>Add by 9 from both sides.</u>
![\Longrightarrow: \sf{-9+4t+9=-17+9}](https://tex.z-dn.net/?f=%5CLongrightarrow%3A%20%5Csf%7B-9%2B4t%2B9%3D-17%2B9%7D)
<u>Then, you solve it.</u>
-17+9=-8
4t=-8
<u>Divide by 4 from both sides.</u>
![\sf{\dfrac{4t}{4}=\dfrac{-8}{4}}](https://tex.z-dn.net/?f=%5Csf%7B%5Cdfrac%7B4t%7D%7B4%7D%3D%5Cdfrac%7B-8%7D%7B4%7D%7D)
<u>Solve.</u>
<u>Divide the numbers from left to right.</u>
-8/4=-2
![\Longrightarrow: \boxed{\sf{t=-2}}](https://tex.z-dn.net/?f=%5CLongrightarrow%3A%20%5Cboxed%7B%5Csf%7Bt%3D-2%7D%7D)
- <u>Therefore, the correct answer is t=-2.</u>
