You can solve by subtracting the sets of coefficients and their variables, and then dividing:

8x - 12 = 4x
-8x -8x
—— ——
-12 = -4x
—- ——
-4 -4

3 = x

Hope this helps! :)

Jackie has 10 groups of pennies with 3 pennies in each group. Carlos has 5 groups of pennies with 100 pennies in each group. Who
Tcecarenko [31]
Answer=Carlos

If Jackie has 10 groups, with 3 in each groups, she has 30 total pennies.

10*3=30 pennies

If Carlos has 5 groups with 100 in each group, then Carlos has 500 pennies.

5*100=500 pennies

500 pennies is more than 30 pennies, so Carlos has more pennies

Pls help?!?!?!?!?!??!!
harkovskaia [24]

Answer:

m<A = 120°

m<C = 45°

Step-by-step explanation:

We can use the triangle sum theorem to find the measures of the angles.

m<A + m<B + m<C = 180°

Then substitute in their given values.

12x + 12 + 15 + 3x + 18 = 180°

Now simplify the equation and you get

15x + 45 = 180°

Continue to solve

15x = 135

x = 9°

Now substitute this value of 9 for the angle expressions of <A and <C

(12 x 9) +12 = m<A

m<A = 120°

(3 x 9)+ 18 = m<C

m<C = 45°

Hope this helps. To check your answer you can add up all the answers to see if it equals 180°.
