6d + 7 = 61 what does d equal?
Answer:
i would reword this to 6x+7=61
Step-by-step explanation:
So.
move the 7 to the right side of the equation but as an opposite number so in this case its gonna be a negative
61-7=54
then you divide the number and get your missing numbers
54/6=9
d=9
plug it in
6(9)+7=61

Steve decreased the number of miles he ran from 25 to 18. By what percent did the number of miles decrease?
Answer:
28%
Step-by-step explanation:
1) 25-18=7(your decreased value)
2) 7(decreased value of miles ran)/25(overall number of miles ran)
3) 7/25*4/4 (this will make the denominator 100)=28/100=28%

Is the ordered pair (-3, 16) a solution for y=-3x + 7?
Answer: Yes
Step-by-step explanation:
(-3, 16) split into place would give you 16= -3-3 + 7. A negative times a negative is always a positive number so, -3 x -3 = 9, 9+7=16
how do you find the volume of a cylinder describe which measurements of the cylinder you need to know
Answer:
To calculate the volume of a cylinder, you need to know its height and the area of its base. Because a cylinder is a flat-top figure (a solid with two congruent, parallel bases), the base can be either the top or bottom

Write the sum, and then write an equivalent expression by collecting like terms and removing parentheses
b. 2x - 7 and the opposite of 2x
Answer :
Sum = 2x-7 + (-2x) and equivalent expression = -7
Step-by-step explanation:
First number is (2x-7) and other number is opposite of 2x i.e. (-2x).
We need to write the sum of 2x - 7 and the opposite of 2x
Opposite of 2x is (-2x)
Sum means to add the number :
2x-7 + (-2x)
Removing parentheses,
2x-7 - 2x
Taking like terms together,
2x-2x-7= 0-7
= -7
Hence, the answer is -7.

A line has a slope of 6 and a y-intercept of 5. What is its equation in slope-intercept form?
Write your answer using integers, proper fractions, and improper fractions in simplest form.
Answer:
The equation in slope-intercept form is y = 6x + 5
Step-by-step explanation:
The slope-intercept form of the linear equation is y = m x + b, where
m is the slopeb is the y-interceptLet us solve the question
∵ A line has a slope of 6
∵ m is the slope of the line
∴ m = 6
∵ The line has a y-intercept of 5
∵ b is the y-intercept
∴ b = 5
→ Substitute the values of m and b in the slope-intercept form
∵ y = m x + b
∴ y = 6x + 5
∴ The equation in slope-intercept form is y = 6x + 5

Rahan is on holiday in the USA. He has $200 to spend on clothes.
Rehan buys. 1 pair of trainers costing $60. 3T. shirts costing $25 each.
He also wants to buy a jacket costing $80
Has Rehan got enough money to buy the jacket
Rahan doesn't have enough money that'll be required in buying the jacket.
Total Amount with Rahan = $200
Total amount of expenses = (1 × $60) + (3 × $25) + $80
= $60 + $75 + 80.
= $215
In this case, since Rahan has $200, then he doesn't have enough money that he'll use in buying the jacket.

Answer:
315 beads
Step-by-step explanation:
The question above is calculated as:
25 necklaces = 375 beads
21 necklaces = x beads
Cross Multiply
25x = 21 × 375
x = 21 × 375/25
x = 7875 / 25
x = 315 beads
Hence, Jared used 315 beads to make 21 necklaces yesterday

An orange cone has an
exact volume of 1207T ft3.
What is the height of the
cone if the radius is 6 ft?
Answer:
32.01 ft
Step-by-step explanation:
Step one:
given data
Volume of 1207T ft3.
the radius is 6 ft
Step two:
The volume of a cone is given as
[tex]V=1/3 \pi r^2h[/tex]
substitute
1207= 1/3*3.142*6^2*h
1207= 37.704h
divide both sides by 37.704
1207/37.704= h
h= 32.01 ft

A battery factory typically produces 12,000 batteries per day and uses 50 boxes for packing the battiest. If the number of boxes needed for packing is proportional to the number of batteries produced, how many more boxes would be needed in a day when 18,000 battiest are produced
Answer:
Number of extra boxes= 120
Step-by-step explanation:
Giving the following information:
Batteries per box= 50
Number of batteries= 18,000
Number of batteries in ecxess= 6,000
We need to calculate the number of boxes required to cover the 6,000 extra batteries:
Number of extra boxes= number of batteries / batteries per box
Number of extra boxes= 6,000 / 50
Number of extra boxes= 120
