Answer:
a = 19
Step-by-step explanation:
a+5/3 (Note: this means a+5 over 3, as in a fraction.)
3 x 8 = a + 5
24 = a + 5
24 + (-5) = (a + 5) + (-5)
19 = (a + 5) - 5
19 = a + 5 - 5
19 = a
a = 19

415 + d ≥ 500
I believe that's the inequality since they want to raise a minimum of $500 so that means it can be more than $500. Hope I helped.
Answer:
<h2>$160</h2>
Step-by-step explanation:
Step one:
For Sadie
initial savings balance= $70
weekly savings = $18
Let S represent the amount of money Sadie has saved
and t the number of weeks after the beginning of the year
The total amount in savings after t weeks is
S=18t+70-------1
For Jack
initial savings balance= $90
weekly savings = $14
Let J represent the amount of money Jack has saved
and t the number of weeks after the beginning of the year
The total amount in savings after t weeks is
J=14t+90---------2
Step two
equation 1 and 2 to find t
18t+70=14t+90
18t-14t=90-70
4t=20
divide both sides by 4
t=20/4
t=5 weeks
so after 5 weeks Sadie and Jack will have the same amount of money
For Sadle t=5
S=18(5)+70-------1
S=90+70
S=$160
For Jack t=5
J=14(5)+90---------2
J=70+90
J=160
The two equations above shows that after 5 weeks their savings will be $160
Store A because 40% off of 120$ will equal 72.
Answer:total area
32 multiply by 18=576
Then to get the cost of painting you divide 576/50=11.32
