Answer:
x = 11
Step-by-step explanation:
Properties of a square,
1). Diagonal of a square bisect the opposite angles.
2). All interior angles of a square measure 90°.
From these properties,
m∠PQR = 90°
Since, diagonal QS bisects angle PQR,
m∠PQS = m∠RQS = 45°
(6x - 21)° = 45°
6x = 45 + 21
6x = 66
x = 11
Answer:
$8.50
Step-by-step explanation:
Divide the price by size so 22.10/2.6!
We have -4(x - 6) + 3(a - 7) = -4x + 24 + 3a - 21 = -4a + 3a + 3
so the answer is B
ok done. Thank to me :>
Step-by-step explanation:
y varies as x^2
y=75/8
x=5
x^2=5^2=25
y=kx^2
k= constant
75/8=25k
cross multiply
8*25k=75
200k=75
k=75/200=15/40=3/8
therefore k=3/8.
equation bonding x and y =
x=3/8y
x=5. 5=3/8y
3=40y. therefore y=3/40.
when x is 2
2=3/8y
16y=3
y=3/16
