Mr.gilliam is 3 years younger than his wife.the sum of their ages is 95.how old is mr.gilliam
Usimov [2.4K]
X = the age of Mr. Gilliam
His wife is 3 years older, so the age of Mr. Gilliam's wife = x+3
The sum of their ages is 95.

x+x+3=95 \\
2x+3=95 \\
2x=95-3 \\
2x=92 \\
x=46

Mr. Gilliam is 46 years old.

One day last week, 6 teachers joined 5/7 of the members of the running club in an after-school run. Priya counted a total of 31
Blababa [14]

Answer:

The running club has 35 members

Step-by-step explanation:

Let

x ----> the total members of the running club

we know that

The total members of the running club multiplied by 5/7 plus 6 must be equal to 31 people

so

\frac{5}{7}x+6=31

Solve for x

\frac{5}{7}x=31-6

\frac{5}{7}x=25

x=25(7)/5

x=35\ members

therefore

The running club has 35 members

Solve the system by the substitution method. Show your work. 2y - x = 5, x2 + y2 - 25 = 0
Anna71 [15]
Subsitution

2y-x=5
minus 2y both sides
-x=5-2y
times -2 both sides
x=2y-5

subsitute 2y-5 for x in other equation

(2y-5)²+y²-25=0
expand
4y²-20y+25+y²-25=0
5y²-20y=0
factor
5y(y-4)=0
set to zero

5y=0
y=0

y-4=0
y=4


subsitute back

for y=0
x=2y-5
x=2(0)-5
x=-5
one solution is (-5,0)

for x=4
x=2y-5
x=2(4)-5
x=8-5
x=3
one solution is (3,4)




the 2 soltuions are (-5,0) and (3,4)

3/20<br> 4x + 2(x - 6) = 12
Nat2105 [25]

Answer:

4x+2(x-6)=12

4x {}^{2}  - 24 + 2x - 12 = 12 \\ 4x {}^{2}   - 36 + 2x = 12 \\ 4x {}^{2}  + 2x = 12 + 36 \\ 4x {}^{2}  + 2x = 48 \\ 4x { }^{2}  + 2x - 48 = 0
