Answer:
-2
Step-by-step explanation:
Subtract 10 on both sides:
6x +10= -2
-10 -10
6x = -12
Divide by 6 on both sides:
6x = -12
/6 /6
x = -2
Answer:
a=4
b=-6
Step-by-step explanation:
3(2ax-10)=24x+5b
6ax - 30 = 24x + 5b
6a = 24
a = 4
5b = -30
b = -6
check: 3(2*4*x - 10) = 24x - 30 = 24x + 5 * (-6) = 24x - 30

Answer:
$64.15
Step-by-step explanation:
to solve this problem, first we should figure out how much money that the cashier gave them back, and then subtract that from $80 (which was what Matt and his siblings gave the cashier) to find out how much the perfume cost.
it is given that:
they gave the cashier $80.
the cashier gave them back 1 ten-dollar bill ($10), 1 five-dollar bill ($5), 8 dimes ($0.80 or 80 cents) , and 1 nickel ($0.05 or 5 cents)
$10+$5+$0.80+$0.05=$15.85
the total amount of money that the cashier gave them back is $15.85
to find how much the perfume cost:
$80-$15.85=$64.15
so, the perfume cost $64.15
Answer:
∠ 3 = 110°
Step-by-step explanation:
The measure of the tangent- chord angle is half the the measure of its intercepted arc.
intercepted arc = 360° - 140° = 220°
∠ 3 = 0.5 × 220° = 110°
