Answer:
10
Step-by-step explanation:
25% is the same as 0.25 so multiply 40 by 0.25.
No more than in terms of math means less than or equal to.
P = 2l + 2w
{96 ≤ 2l + 2w
{L ≥ w - 4
Here we see a system of linear inequality in two variables.
You finish.
Answer:
35.5 is the average of 34 and 37
Step-by-step explanation:
Answer:
y=1/2x
Step-by-step explanation:
Answer:
x = 1 and y = −2
Step-by-step explanation:
Rewrite equations:
x + 2y = −3
3x − 2y = 7
Step 1: Solve x+2y=−3 for x:
x + 2y = −3
x + 2y + −2y = −3 + −2y (Add -2y to both sides)
x = −2y − 3
Step 2: Substitute −2y − 3 for x in 3x − 2y = 7:
3x − 2y = 7
3(−2y − 3) − 2y = 7
−8y − 9 = 7 (Simplify both sides of the equation)
−8y − 9 + 9 = 7 + 9 (Add 9 to both sides)
−8y = 16
−8y/−8 = 16/−8 (Divide both sides by -8)
y = −2
Step 3: Substitute −2 for y in x = −2y − 3:
x = −2y − 3
x = (−2)(−2) − 3
x = 1 (Simplify both sides of the equation)
