Both sides left and right are equal because they have equal angles.

2x-5=x+40

x=45.

plug in to be sure.

2(45)-5= 85
&

Answer:

D) 18 bags of chips and 6 jars of salsa

Step-by-step explanation:

Given : The networking organization you joined is throwing a party. You are in charge of buying the chips, which cost $2.50 per bag and salsa, which costs $4 per jar. The chips & salsa budget you are given totals $60.

Inequality: $2.5x+4y$ ≤ $60$

Solution :

x represents chips

y represents salsa

Option a: 10 bags of chips and 2 jars of salsa

so, x = 10 and y =2

Putting values in inequality

$2.5(10)+4(2)$ ≤ $60$

$25+8$ ≤ $60$

$33$ ≤ $60$

Hence it is correct.

Option c : 14 bags of chips and 5 jars of salsa

so, x = 14 and y =5

Putting values in inequality

$2.5(10)+4(2)$ ≤ $60$

$50+8$ ≤ $60$

$58$ ≤ $60$

Hence it is correct.

Option c : 14 bags of chips and 5 jars of salsa

so, x = 14 and y =5

Putting values in inequality

$2.5(14)+4(5)$ ≤ $60$

$35+20$ ≤ $60$

$55$ ≤ $60$

Hence it is correct.

Option d :18 bags of chips and 6 jars of salsa

so, x = 18 and y =6

Putting values in inequality

$2.5(18)+4(6)$ ≤ $60$

$45+24$ ≤ $60$

$69\geq 60$

Hence it is not correct since it violates the inequality

V = 120 in^3

Here is why:

The volume formula for a pyramid is:

$V=\frac{1}{3}Bh$

The B stands for the area of the base, which in this case is a right triangle. We will find the area of the right triangle first, then plug it into the equation.

The area formula for a triangle is:

$A=\frac{1}{2}bh$
