To solve for x,
4.7x = 2.5x + 8.8
minus 2.5x from both sides:
2.2x = 8.8
divide both sides by 2.2:
2.2x/2.2 = 8.8/2.2
simplify:
x = 4
Answer:
t = 6 4/25 hours
Step-by-step explanation:
The formula to find out how long it takes them to do the job is
1/m + 1/ a = 1 /t
where m is the time for Matthew to do the job
a is the time for Arianna to do the job
and t is the time for them to do the job together
m = 14 hours
a = 11 hours
Substituting what we know
1/14 + 1/11 = 1/t
Multiplying by 154t (14*11*t) so we can clear the fractions
154t*(1/14 + 1/11) = 1/t* 154t
11t + 14t = 154
Combine like terms
25t = 154
Divide by 25
t = 154/25
t = 6 4/25 hours
I think its 32,000,
320,000 - 10% = 288,000 - 320,000 = 32,000
Answer:
<h2><u><em>
49.75$</em></u></h2>
Step-by-step explanation:
You save 25% on a $199 television. How much do you save?
25% = 1/4
so
199 : 4 = 49.75$
Answer:
(x + 2)(x - 4)
Step-by-step explanation:
Given the zeros of a function, say x = a and x = b, then
the factors are (x - a) and (x - b)
From the graph
The zeros are x = - 2 and x = 4, thus the factors are
(x - (- 2)) and (x - 4), that is (x + 2) and (x - 4)
