To answer this question you would need to use PEMDAS. Since you don't have any parentheses or exponents, you would start by doing all division from left to right. After that you would do the subtraction from left to right. Your final answer should be -13.5
Answer:
Step-by-step explanation:
Amount invested 39000 dollars
Let x be invested at 8% and y at 9.5%
Then interest on X = 0.08x and interest of Y =0.095 Y
The equations that connect x and y are
![x+y =39000\\-0.08x+0.095y=467.50](https://tex.z-dn.net/?f=x%2By%20%3D39000%5C%5C-0.08x%2B0.095y%3D467.50)
Multiply second equation by 100 and I equation by 8
![8x+8y = 312000\\-8x+9.5y=46750\\----------------------\\17.5y =358750\\y=20500](https://tex.z-dn.net/?f=8x%2B8y%20%3D%20312000%5C%5C-8x%2B9.5y%3D46750%5C%5C----------------------%5C%5C17.5y%20%3D358750%5C%5Cy%3D20500)
![x = 39000-20500 = 18500](https://tex.z-dn.net/?f=x%20%3D%2039000-20500%20%3D%2018500)
18500 at 8% and 20500 at 9.5%
Answer:
4/5x(v-7)=2
multiply both sides by 5/4, the reciprocal of 4/5
v-7=2x(5/4)
Express 2x(5/4) as a single fraction
v-7=<u>2</u><u>x</u><u>5</u>
4
Multiply 2 and 5
v-7=<u>1</u><u>0</u>
4
Reduce the fraction 10/4 to the lowest by extracting and cancelling 2
v-7=<u>5</u>
2
Add 7 to both sides
v=<u>5</u>+7
2
Covert fraction to 14/2
v=5/2+14/2
Since 5/2 and 14/2 have the same denominator, add them by adding their numerators
v=<u>5</u><u>+</u><u>1</u><u>4</u>
2
Add 5 and 14 together
v=<u>1</u><u>9</u>

Answer:
A The area of both figures are equal.
B. The area of the rectangle is 15 m2.
Step-by-step explanation:
Area of rectangle:
Base × height
5 × 3 = 15 units²
Area of triangle:
½ × base × height
½ × 6 × 5 = 15 units²
Answer:
12
Step-by-step explanation:
plug in -7 where x is
5 - (-7) = 12
