Answer:
The answer is 3.6
Step-by-step explanation:
Step one:
Singer A is offering his services for an initial $95 in addition to $12.95 per hour
let the number of hours be x and the total charge be y
the expression for the total for singer A is
y=12.95x+95----------2
Singer B is offering her services for an initial $99 in addition to $11.85 per hour
let the number of hours be x and the total charge be y
the expression for the total for singer A is
y=11.85x+99----------2
Step two:
Equating 1 and 2 we have
12.95x+95=11.85x+99
collect liker terms
12.95x-11.85x=99-95
1.1x=4
divide both sides by 1.1
x= 4/1.1
x=3.63
to the nearest tenth it is 3.6
Answer:
x+4 square meters
Step-by-step explanation:
In general, when we have two expressions and :
In words, the coefficent of the middle term is the <em>sum</em> of a and b, and the last term is the <em>product</em> of a and b. In our given expression:
Thankfully, we're already given one of these terms: . Solving for b in that first equation, we get
9 × 4 is 36, so this result checks out! So, with a length of meters, our width must be meters.
Volume of the cube = x³
Volume of the cuboid =x*2*5=10x
V(cube) - V(cuboid) = 100
x³ - 10x =100
