340.1 ÷ 9.5 = 358
Answer:
35.8
Step-by-step explanation:
[tex]\frac{340.1}{9.5}[/tex] = 358
We know that our answer can never be greater than 358 since the dividend
is 340.1 and the divisor is 9.5;
Also,
Both values are to one decimal places and we can use this to solve the problem;
9 can divide 340 in about 37 place with a remainder of 7,
So, it is appropriate to make the solution 35.8

t + 17 = 3
show work
Answer:
t=-14
Step-by-step explanation:
subtract 17 from each side
Answer:
t = -14
Step-by-step explanation:
to find out the answer, you need to get t by itself and to do that you subtract 17 from both sides. On the left side, it cancels out and on the right, 3-17 is -14 so t would equal -14
The post office sold 39-cent
commemorative stamps in sheets
of 25 stamps. What was the price
for the sheet of stamps?
Answer: $9.75.
Step-by-step explanation:
Given: Cost per stamp = 39 cents
since 1 dollar = 100 cent , so 1 cent = 0.01 dollar
So, Cost per stamp = $0.39
Total stamps = 25
Cost of 25 stamps = (Cost per stamp) x (Cost per stamp)
=$0.39 x 25
= $9.75
Hence, the price for the sheet of stamps = $9.75.

What is 708 divided by 67 with a remainder?
Answer:
its 10 with the remainder of 38
Step-by-step explanation:
The result of the division is remainder = 38 and quotient = 10
What is division?Division is the opposite of multiplying. When we know a multiplication fact, we can find a division fact: Example: 3 × 5 = 15, so 15 / 5 = 3. Also, 15 / 3 = 5.
Given that, 708 divided by 67
When dividing 708 by 67 will get 10 as quotient and 38 remainder
Hence, the result of the division is remainder = 38 and quotient = 10

Find the slope of AB: A(-2, 5) and B(6.-1)
Answer:
Step-by-step explanation:
y2- y1/x2-x1
-1-5/6-2
-6/8
The required slope of AB is -3/4 which passes through points A(-2, 5) and B(6.-1).
What is the slope of the line?The slope of the line is defined as the angle of the line. It is denoted by m
Slope m = (y₂ - y₁)/(x₂ -x₁ )
Assume two points on a line—Point 1 and Point 2. Point 1 has coordinates (x₁,y₁) and Point 2 has coordinates (x₂, y₂)
To determine the slope of AB: A(-2, 5) and B(6.-1)
Given,
We have been given that two points are A(-2, 5) and B(6.-1)
Let
x₁ = -2, y₁ = 5
x₂ = 6, y₂ = -1
∵ Slope m = (y₂ - y₁)/(x₂ -x₁ )
Substitute values in the formula
The slope of AB = (-1 - 5)/(6 - (-2))
The slope of AB = (-6)/(6 + 2)
The slope of AB = -6/8
Therefore, the required slope of AB is -3/4.

Chloe makes a long distance call from a pay phone, the first minute of a call cost $2.30. After that, each additional minute is $0.20. How many minutes can Chloe talk for $4.30?
Answer:
The number of minutes is 10minutes
Step-by-step explanation:
Step one:
Given that the first minute of a call cost $2.30 and
each additional minute is $0.20.
let the number of minutes be x
and the total cost be y
the total cost for the situation is modeled as
y=mx+c-----equation of a line
Step two:
given that y=4.3, we can solve for the totals cost as
by substituting we have
4.3=0.2x+2.3
4.3-2.3=0.2x
2=0.2x
x=2/0.2
x=10
The number of minutes is 10minutes

Answer:
n = 12
Step-by-step explanation:
84 / 7 = 12
May I have brainliest please? :)
Answer:
84 is 7 x n.
n = 84 ÷ 7
n = 12
Step-by-step explanation:
You can solve the problem by using algebraic expressions in looking for the value of n.
Let n be the no. of families in City B that have a dog.
City A is 7 times as many families with a dog than City B. You can express this as: City A = 7 x n
Since you know that City A has 84 families owning a dog. Then you can express this as: 84 is 7 x n or 84 = 7 x n.
Let's get the value of n.
84 = 7 x n
n = [tex]\frac{84}{7}[/tex] or n = 84 ÷ 7
n = 12
There are 12 families in City B that have a dog.
