Chris: x + 3 (x + 3) - 2 = x + 1

Nathan: 18 (18) - 2 = 16

Jacob: x (x) - 2 = x - 2

Chris + Nathan + Jacob = sum

x + 1 + 16 + x - 2 = 59

2x - 15 = 59 added like terms (x and x) and (1, 16, and -2)

2x = 74 added 15 to both sides

x = 37 divided both sides by 2

Answer: Jacob is 37 yrs old

Two friends shop for fresh fruit. Elena buys a watermelon for $7.45 and 3 pounds ofcherries. Taniy buys a pineapple for $3.35 an

Scrat [10]

Let's use the variable E to represent the total value spent by Elena and T to represent the total value spent by Taniy.

If Elena spent $7.45 plus the cost of 3 pounds of cherries, the expression for the amount she spent is:

$E=7.45+3p$

Taniy spent $3.35 plus the cost of 2 pounds of cherries, so the expression for the amount the spent is:

$T=3.35+2p$

To find how much more Elena spent, let's subtract both expressions:

$\begin{gathered} E-T\\ \\ =7.45+3p-(3.35+2p)\\ \\ =7.45+3p-3.35-2p\\ \\ =4.1+p \end{gathered}$

Therefore the answer is 4.1 + p.

What is Z 2(2z -4)=4

Pachacha [2.7K]

Answer:

z=3

Step-by-step explanation:

2(2z -4)=4

Divide by 2

2/2(2z -4)=4/2

2z-4 = 2

Add 4 to each side

2z-4+4 = 2+4

2z = 6

Divide by 2

2z/2 = 6/2

z=3

If triangle ABC is similar to triangle PQR, find the value of x and y.

tester [92]

Answer:

x = 9

y = 6

Step-by-step explanation:

ΔABC ~ ΔPQR

Therefore, corresponding sides of these similar triangles will be in the proportional.

$\frac{AB}{PQ}=\frac{BC}{QR}= \frac{AC}{PR}$

$\frac{6}{x}= \frac{4}{y}= \frac{8}{12}$

$\frac{6}{x}= \frac{8}{12}$

x = $\frac{12\times 6}{8}$

x = 9

Similarly, $\frac{4}{y}= \frac{8}{12}$

y = $\frac{12\times 4}{8}$

y = 6
