Answer:

Step-by-step explanation:

Your problem can be described in the following equation

$139 + $15x = $319

139 dollars + 15 dollars (times x (the number of weeks)) = 319

319 - 139 = 180

180 / 15 = 12

x = 12

Mr's Rodman's class sold candy bras for $1.25 each and Mr's Powell's class sold water bottles for $0.75 each to raise for the ma

Anvisha [2.4K]

The equation system is

1.25x+0.75 (92-x)=87.5

Solve for x

1.25x+69-0.75x=87.5

0.5x+69=87.5

0.5x=87.5-69

0.5x=18.5

X=18.5÷0.5

X=37 units of candy bras

(92-37)=55 units of water bottles

Mr's Powell's class sold more items

Let's look which class earned more

Mr's Powell's class earned

55×0.75=41.25

Mr's Rodman's class earned

37×1.25=46.25

So from above

Mr's Rodman's class earned more

Hope it helps!

∠A and \angle B∠B are complementary angles. If m\angle A=(4x+24)^{\circ}∠A=(4x+24) ∘ and m\angle B=(3x-4)^{\circ}∠B=(3x−4) ∘ , t

Ostrovityanka [42]

Answer:

Step-by-step explanation:

∠A and ∠B being complementary means m∠A + m∠B = 90°

4x + 24 + 3x - 4 = 90

7x + 20 = 90

7x = 70

x = 10

m∠B = (3•10 - 4)° = 26°
