One number is 5 times a first number. A third number is 100 more than the first number. If the sum of the three numbers is 779,

Harrizon [31]

Answer:

97, 485, 197

Step-by-step explanation:

Given:

First number = a
Second number = b
Third number = c

Then we have:

b = 5a
c = 100+a
a + b + c = 779

Substituting b and c in the third equation:

a + 5a + 100+a = 779
100 + 7a = 779
7a = 779- 100
7a=679
a= 679/7
a = 97
b= 5*97 = 485
c = 100+ 97 = 197

To answer this question, try to solve the system of equations. Start by plugging in " $x^{2} +3x-7$ " in for y in the second equation:

$x^{2} +3x-7-5x+8=0$

*Combine like terms*

$x^{2} -2x+1=0$

*Factor*

$(x-1)(x-1)=0$

*Set each term equal to 0*

x-1=0

*Add 1 to both sides*

x=1

C) There is exactly 1 solution.

Hope this helps!!

$\frac{4}{1}$ × $\frac{2}{3}$ = $\frac{8}{3}$
You then divide the numerator(top) by the denominator(bottom)
$\frac{8}{3}$ = $2 \frac{2}{3}$
Your answer is $2 \frac{2}{3}$
