Answer:

8/5 or 3.6

Step-by-step explanation:

1.03x + 3.97x = 5x

So in this equation, it would be:

5x - 5 = 13

Subtract 5 from both side:

5x + 5 - 5 = 13 + 5

5x + 0 = 18

5x = 18

Divide both side by 5

5x/5 = 18/5

1x = 18/5

x = 18/5 or 3.6

Hope this help you :3

Answer:

X = $\frac{18}{5}$ , or X = 3.6

Step-by-step explanation:

For this problem we must isolate x

1.03x+3.97x-5=13 | Add 5 to both sides

1.03x+3.97x=18 | Add the x's

5x=18 | Now divide both sides by 5

x= $\frac{18}{5}$ , x=3.6

Two angels are complementary. One angle is 18 degrees more than 2 times the other. Find the angles.

Ludmilka [50]

Two complementary angles = 90°
X = 18+ 2y
X + y = 90
Plug first equation into second
18 + 2y +y = 90
18 + 3y = 90
18 – 18 +3y = 90 – 18
3 y = 72
3y/3 = 72/3
Y = 24
Plug y into 2nd formula
X + 24 = 90
X + 24 -24 = 90 – 24
X = 66

3b-14/3b = 5b+2/3b b= ?

WINSTONCH [101]

First of all, observe that all fractions exist as long as b is not zero.

Multiply both numerator and denominator of the first fraction by 3:

$\dfrac{3b-15}{3b}+\dfrac{1}{3b}=\dfrac{5b+2}{3b}$

Now all fractions have the same denominator. Under the assumption that b is not zero, multiply both sides by 3b:

$3b-15+1=5b+2 \iff 3b-14=5b+2$

Subtract 3b from both sides:

$-14=2b+2$

Subtract 2 from both sides:

$-16=2b$

Divide both sides by 2:

$b=-8$
