Answer:
(12, 487)
Step-by-step explanation:
y = 3.7x + 442 ----› Eqn. 1
y = 14.4x + 312 ----› Eqn. 2
Substitute y = (3.7x + 442) into eqn. 2.
y = 14.4x + 312 ----› Eqn. 2
3.7x + 442 = 14.4x + 312
Collect like terms
3.7x - 14.4x = -442 + 312
-10.7x = -130
Divide both sides by -10.7
x = 12.1495327
Substitute x = 12.1495327 into eqn. 1.
y = 3.7x + 442 ----› Eqn. 1
y = 3.7(12.1495327) + 442
y = 486.953271
The solution to the system is rounded to the nearest integer:
(12, 487)
Divisible by 5 and 9 as 9x5=45 so that is the answer.........
It should be 24.5%. If you divide 98 by 400 it's .245. Then multiply it by 100, you get 24.5%.
Answer:
Given: PR=EF, QR=DE and PQ=FD
Now, In △PRQ and △DEF
PR=EF
QR=DE
PQ=FD
Thus, △PQR≅△FDE (SSS rule).
Answer:
$118.43
Step-by-step explanation:
The price on Monday ($126.38), less the decrease ($7.95), results in the price on Tuesday:
