Step-by-step explanation:
Cross Multiply - 15 times 42 = 630
630 = 21t
What is 630 / 21... = 30
t = 30
Answer:
t=3021/15=42/t
Rewrite the equation as 42/t=21/15.
42/t=21/15
Cancel the common factor of 21 and 15.
42/t=7/5
Multiply the numerator of the first fraction by the denominator of the second fraction. Set this equal to the product of the denominator of the first fraction and the numerator of the second fraction.
42⋅5=t⋅7
Solve the equation for t.
t=30

What is the equation of the line that passes through the point (3,-2) and has a
slope of -22
Answers
Answer:
y = -2x + 4
Step-by-step explanation:
slope intercept form:
y = mx + b
m = slope = -2
b = y-intercept
x = x = 3
y = y = -2
Plug in the corresponding numbers to the corresponding variables:
-2 = (-2) * (3) + b
Simplify. First, multiply:
-2 = (-6) + b
Next, isolate the b. Note the equal sign, what you do to one side, you do to the other. Add 6 to both sides of the equation:
-2 (+6) = -6 (+6) + b
b = -2 + 6
b = 4
Plug in 4 for b in the equation:
y = mx + b
y = -2x + 4

You recycled a total of 30 cans and bottles and made $1.80. For cans you get $0.05 and for bottles
you get $0.15. How many cans did you recycle?
Answers
Answer:
27
Step-by-step explanation:
x + y = 30
0.05x + 0.15y = 1.80
x = 30 - y
1.5 - 0.05y + 0.15y = 1.80
0.10y = 0.30
y = 3 (bottles)
x = 27 (cans)

solve 35% of 84 using the mental method
Answers
Answer:
29 approximately
Step-by-step explanation:
You want to estimate 35% of 84. 35% is roughly equivalent to 1/3, so multiply 84 by 1/3 (or, equivalently, divide 84 by 3), obtaining 28. Use a calculator to find 0.35(84): 29.4. This 28 is a fairly good estimate of 35% of 84 which is 29.4.

A pizza with a diameter of 8 inches costs $10 and a pizza
with a radius of 5 inches costs $12. Which pizza is the
best buy (square inches per dollar)?
Answers
Answer:
8 inch is your best buy
Step-by-step explanation:
8inch diameter =10 dollars
5 inch radius = 12 dollars
so if we get each equal to the diameter it should be 10 inch and that would be 24 dollars vs . 8 in for 10 dollars. So best buy would be 8 inch

Answers
Answer:
350 people can fit into 42 rooms
Step-by-step explanation:
So we can write it as a relation fraction equation:
[tex]\frac{50}{6}=\frac{x}{42}[/tex]
Where:
x represents the people can fit in 42 rooms
[tex]x=\frac{50*42}{6}[/tex]
[tex]x=350[/tex]
Therefore, 350 people can fit into 42 rooms.
