Answer:
<h2>
7x + 9 + 5x + 3 = 180</h2>
Step-by-step explanation:
its a supplementary angles:
so the equation is add the two equation equals to 180
7x + 9 + 5x + 3 = 180
You save 5 cents per ounce by using the 40 ounce jar, because if you do $5.20 divided by 40 it equals $0.13 but if you do $2.70 divided by 15 it equals $0.18 which is 5 more cents the the 40 ounce
Answer:
16
Step-by-step explanation:
64 divided by 4 is 16. Paul has 16 baseball cards.
Bicycle has 2 wheels and 2 pedals
tricycle has 3 wheels and 2 pedals
EQ 1 : 2b + 2t = 170 pedals
EQ 2: 2b +3t = 206 wheels
subtract EQ 1 from EQ 2
2b +3t = 206 - 2b + 2t = 170 = t=36
there were 36 tricycles
36 x 2 = 72 pedals
170 pedals - 72 = 98 pedals left
98/2 = 49 bicycles
36 Tricycles and 49 bicycles
Answer:
A = $1,545.00
(I = A - P = $45.00)
Equation:
A = P(1 + rt)
Explanation:
First, converting R percent to r a decimal
r = R/100 = 4%/100 = 0.04 per year.
Putting time into years for simplicity,
9 months / 12 months/year = 0.75 years.
Solving our equation:
A = 1500(1 + (0.04 × 0.75)) = 1545
A = $1,545.00
The total amount accrued, principal plus interest, from simple interest on a principal of $1,500.00 at a rate of 4% per year for 0.75 years (9 months) is $1,545.00.
