Answer:

The measure of the angles:

24° and 66°

Step-by-step explanation:

Complementary angles sum 90°

then:

(3x + 3) + (10x-4) = 90

3x + 10x + 3 - 4 = 90

13x - 1 = 90

13x = 90+1

13x = 91

x = 91/13

x = 7°

then:

angle 1:

3x+3 = 3*7 + 3 = 21+3 = 24°

angle 2

10x - 4 = 10*7 - 4 = 70 - 4 = 66°

Check:

66° + 24° = 90°

hELP!!! PLEASE?! BRAINLIEST ANSWER INCLUDED!!! A cashier has a total of 98 bills, made up of fives and fifties. The total value

Yanka [14]

Answer:

84 5$ bills and 42 $10 bills

Step-by-step explanation:

The problem has two variables, let:

F=number of $5 bills

T=number of $10 bills

Translate:

"a total of 126 bills, made up of fives and tens" means

126 = F + T (the number of each)

"total value of the money is $800" means

5F + 10T = 800 [use $10 and $5 times the number of bills]

Now, solve for either T or F in the first equation and put that into the second equation:

T = 126 - F

5F + 10(126-F) = 800 [now, all expressed in terms of F so we can solve for F]

5F + 1260 -10F = 800 [distribute]

-5F = -460 [subtract 1260 from both sides]

F = 92 [divide both sides by -1]

Now, put that value into either of the equations to solve for T (the second equation looks easy):

T = 126 - F

T = 126 - 92

T = 34

Checking (very important):

Is 126 = 92 + 34 ?

126 = 126 ? yes

Is 5(92) + 10(34) = 800 ?

460 + 340 = 800 ?

800 = 800 ? yes
