Answer:
$0.45
Step-by-step explanation:
Unit price is basically the same as unit rate. Unit rate is the cost of one item.
So $3.15 divided by seven is point fourty-five.
Step-by-step explanation:
Given that the first number is
5,555 and
the second number is 4,444
the product of 5,555 and4,444= 24686420
to the nearest thousand 5,555= 6000
to the nearest thousand 4,444= 5000
Therefore the product of 6000 and 5000 is
=6000x5000
=30000000
Answer: 1.25
Step-by-step explanation:
To solve this, we.will use the formula,
y = kx
where,
y = water depth
k = constant of proportionality
x = time
Using y = kx
2.5 = 2k
k = 2.5/2
k = 1.25
Also,
y = kx
3.75 = 3k
k = 3.75/3
k = 1.25
Answer:
x = 42
Step-by-step explanation:
Cross multiplying is done as follows:
<em>the </em><em>denominator </em><em>of the second </em><em>fraction </em><em>is </em><em>multiplied </em><em>with the </em><em>numerator </em><em>of the first </em><em>equation</em> and <u>denominator of the first fraction is multiplied with the numerator of the second equation</u>
5(3x+6) = 4(4x-3) multiply inside the parenthesis
15x + 30 = 16x - 12 transfer like terms to same side of the equation
30 + 12 = 16x - 15x
42 = x
