a) x/2 + 4y

= 10/2 + 4*2 = 5 + 8 = 13

b) 3 (p + 2q)

= 3 (8 + 2*3) = 3 (8 + 6 ) = 3* 14 = 42

c) m + n ( q + 3)

= 4.5 + 6 (-1 + 3) = 10.5 * 2 = 21

d) (u+v)^x

= (7 + (-4) ) ^ 4 = (7-4)^4 = 3^4 = 81

Hope it helps u

Solve the system of equations for the variables: 5x+2y=13 x+2y=9

r-ruslan [8.4K]

Answer:

x = 1

y = 4

Step-by-step explanation:

5x + 2y = 13

x + 2y = 9

Add both equations.

6x + 4y = 22

Solve for x.

6x = 22 - 4y

x = 22/6 - 4/6y

Put x as 22/6 - 4/6y in the second equation and solve for y.

22/6 - 4/6y + 2y = 9

-4/6y + 2y = 9 - 22/6

4/3y = 16/3

y = 16/3 × 3/4

y = 48/12

y = 4

Put y as 4 in the first equation and solve for x.

5x + 2(4) = 13

5x + 8 = 13

5x = 13 - 8

5x = 5

x = 5/5

x = 1

Caleb and Mike both score the same amount of points in a game. Caleb has fifteen less than the total number of options. Mike has

zvonat [6]

Answer:
129 points
Step-by-step explanation:
Let L and C represent the scores of Luke and Caleb, respectively.
L = 2C -15 . . . . . Luke scored 15 less than twice the number Caleb did
L +C = 201 . . . . . they scored 201 points altogether
Add twice the second equation to the first:
2(L +C) + (L) = 2(201) + (2C -15)
3L +2C = 387 +2C . . . . simplify
3L = 387 . . . . . . . . . . . . .subtract 2C
L = 387/3 = 129 . . . . . . .divide by 3
Luke scored 129 points.

The head of a nail is circular, as shown. The head of this nail has a diameter of 6 millimeters. Which measurement is closest to

Anastasy [175]

Answer: $\boxed{\ 28.26}$

My step-by-step explanation:

We would use the formula πr2 (pi x radius x radius)

 2.In this problem we were given the diameter of 6, in order to find the radius, you just divide by 2

 And so we find: 6mm÷2=3mm

3. So now that we have our radius, we can just plug the numbers into the formula. So this would be:

πr2= 3.14 x 3 x 3= 28.26mm2

Hope this helps you!
