The part of the solution that is incorrect is (5). This is because -10 -8 = -18. :)

13 POINTS.+Betsey is 11 years older than Waldo. Betsey's age is 15 years less than three times Waldo's age. The system below models the relationship between Betsey's age (b) and Waldo's age (w):

b = w + 11
b = 3w − 15

Which of the following methods is correct to find Betsey's and Waldo's age?
Solve w + 11 = 3w − 15 to find the value of w.
Solve b + 11 = 3b − 15 to find the value of b.

Answer:

Option 1st is correct

Solve w + 11 = 3w − 15 to find the value of w.

Step-by-step explanation:

Here b represents the Betsey's age and w represents the Waldo's age

As per the statement:

Betsey is 11 years older than Waldo. Betsey's age is 15 years less than three times Waldo's age.

The system below models the relationship between b and w:

$b = w+11$

$b = 3w-15$

Equate these equations to solve for w, we have;

$w+11 = 3w-15$

Add 15 to both sides we have;

$w+26= 3w$

Subtract w from both sides we have;

$26= 2w$

Divide both sides by 2 we have;

13 = w

w = 13 years

Substitute in b = w+11 we have;

b = 13 +11 = 24 years.

b = 24 years

Therefore. following methods is correct to find Betsey's and Waldo's age is:

$w+11 = 3w-15$

$w + 11 = 3w - 15 \n 2w=26 \n w=13 \n b = w + 11 \n b = (13) + 11=24$

4h - 6= 22-8s + 1= 33
-4w - 4= 8
5 +1/7b = -2
i need help on these problems!

Answers

4h−6=22
1. Add 6 to both sides.
4h−6+6=22+6
4h=28
2.Divide both sides by 4.
4h/4=28/4
h=7

−8s+1=33
1: Subtract 1 from both sides.
−8s+1−1=33−1
−8s=32
2: Divide both sides by -8.
−8s/−8=32/−8
s=-4

−4w−4=8
Step 1: Add 4 to both sides.
−4w−4+4=8+4
−4w=12
2: Divide both sides by -4.
−4w/−4=12/−4
w=−3

Step 1: Simplify both sides of the equation.
1/7b+5=−2
2: Subtract 5 from both sides.
1/7b+5−5=−2−5
17b=−7
3: Multiply both sides by 7.
7*(1/7b)=(7)*(−7)
b=−49

A movie theater offers popcorn in two different containers for the same price. One container is a trapezoidal prism with a base area of 34 square inches and a height of 5 inches. The other container is a triangular prism with a base area of 35 square inches and a height of 6 inches. Complete the explanation on which is a better deal:The (_trapezoidal or triangular__) prism is a better deal because you get ______ inches cubed for the same price you would pay for _______ inches cubed with a (_trapezoidal or triangular_) prism.

Answers

Given:
Trapezoidal prism: base area = 34 in² ; height = 5 in
Triangular prism: base area = 35 in² ; height = 6 in

Volume of Trapezoidal prism = base area * height
V = 34 in² x 5 in
V = 170 in³

Volume of Triangular prism = base area * height
V = 35 in² x 6 in
V = 210 in³

The TRIANGULAR prism is a better deal because you get 210 inches cubed for the same price you would pay for 170 inches cubed with a TRAPEZOIDAL prism.

Answer:

triangular
