Answer:
There are 91 cookies in the package of cookies
Step-by-step explanation:
The given parameter for the number of cookies are;
The number of cookies left when eating 3 at a time = 1 cookie
The number of cookies left when eating 5 at a time = 1 cookie
The number of cookies left when eating 7 cookies at a time = No cookie leftover
Let 'n' represent the number of cookies in the pack, let 'a', 'b', and 'c' be the multiples of 3s, 5s, and 7s in 'n', respectively, we have;
The number of cookies in the pack, n < 100
Therefore, we have;
3·a = n - 1
5·b = n - 1
7·c = n
∴ n - 1 is a multiples of 3 and 5 less than 100 which are;
15, 30, 45, 60, 75, and 90
Therefore, the possible values of 'n' are'
n = n - 1 + 1 = 15 + 1 = 16, 30 + 1 = 31, 45 + 1 = 46, 60 + 1 = 61, 75 + 1 = 75, 90 + 1 = 91
Multiples of 7 includes;
7, 14, 21, 28, 35, 42, 49, 56, 63, 70, 77, 84, 91, and 98
Therefore, n = 91 which is the number that appear simultaneously in both search
The number of cookies in a package = 91 cookies

Eli's family is going to have
a big go-cart race and each
go-cart takes 3- gallon of
-
gas. If there are 7 go-carts,
how many total gallons of
gas do they need to fill up
all the go-carts?
Answer:
21 gallons
Step-by-step explanation:
You multiply the amount of go-carts(7) by the amount of gas each go-cart takes(3 gallons.) You get 21 gallons for all the go-carts.

Answer:
y=-3x+2
Step-by-step explanation:
y-y1=m(x-x1)
y-(-4)=-3(x-2)
y+4=-3x+6
y=-3x+6-4
y=-3x+2
Glenn needs to cut pieces of ribbon that are each 1 meter long to make ribbon key chains. If he has 6 pieces of ribbon that are each 1 dekameter long, how many 1−meter pieces of ribbon can he cut?
Answer:
2/3
Step-by-step explanation:
Glenn needs to cut pieces of ribbon that are each 1 meter long to make ribbon key chains. If he has 6 pieces of ribbon that are each 1 dekameter long, how many 1−meter pieces of ribbon can he cut?
1 decametre = 10 metres
Hence,
10 meters = 6 pieces of ribbon
1 meter = x pieces
Cross Multiply
10x = 6
x = 6/10
x = 2/3 (1 meter pieces of ribbon)
4x + y = 7 and passes through the point (1, 8)?
Plz hurry!!!!!!!
if 1/4x +2y= 11/4
and - 6y - x = 7, what is
half of y?
Answer:
y/2 = 4.5
Step-by-step explanation:
1/4x + 2y = 11/4
distribute by 4 to eliminate fractions
x + 8y = 11
+ -x - 6y = 7
2y = 18
y = 9
half of 9 = 4 1/2
Jenna bought enough lattes for all her friends. Each latte was $3.50
and she gave the barista a $20 bill, who then gave her back $2.50
in change. Write an equation modeling this, with x as the cost per late
How many lattes did she buy?
Answer: 5 lattes
Step-by-step explanation: Our equation is 20 − 3.5x = 2.5, which means x = 5 lattes.
Answer:
Step-by-step explanation:
y=3.5x (cost function where y is cost and x is the number of lattes)
20-2.5=3.5x
17.5=3.5x
5=x
So she bought 5 lattes.

When doing decimals, what does a dot over a number mean? For example, take 24.671, but theres a small dot over the numbers 6 and 1. What do I do and what does it mean?
Step-by-step explanation:
The dot is called a decimal point. It is also called the decimal separator. It separates whole numbers from fractional numbers.
In this example;
24.671
The numbers before the point, 24 is the whole number
The numbers after the point, 671 are the fractional portion of the number. They represent 6 tenths, 7 hundredths and 1 thousandths.
Also, the number of digits after the point tells you how many decimal place the number is in. In this example the number of decimal places is 3.

Explanation:
4²+4²≠8²
(4+4)²=8²
If you use PEMDAS you can find that 4²+4²=32 not 8² which equals 64
You can also find that (4+4)²=(8)²
∠1 and ∠2 are complementary angles. If ∠1 measures 35º, what is the measure of ∠2?
Answer:
55 degrees
Step-by-step explanation:
Complementary angles are two angles that equal 90 degrees together so if one angle is 35 degrees then the other must be able to add towards that to make 90 degrees
90=35+∠2
-35 -35
55=∠2

Help please Asap!!!
Answer:
4 cm, if you subtract 9 from 13 you get four.
Please no more cap answers, actually need help
Answer:
[tex]\sqrt{8x^{2} }[/tex]+5-3 = 8.12
8.12 rounded to nears whole number is 8
therefore 8.12 rounded down to three decimal places is 8.1
Therefore your answer would be 8.1
If it wont let you add a decimal your answer would also be 8

X+4=19-2x
8z - 20 =z +15
Answer:
1st answer is 6, 2nd is 5, 3rd is 5
Step-by-step explanation:
3x-2=x+10
3x-x=10+2
2x=12
x=12÷2
x=6
x+4=19-2x
x+2x=19-4
3x=15
x=15÷3
x=5
8z-20=z+15
8z-z=15+20
7z=35
z=35÷7
z=5
plzz mark me as brainliest
Answer:
3x-2=x+10
x=6
x+4=19-2x
x=5
8z-20=z+15
z=5
Step-by-step explanation:
3x-2=x+10
+2 on both sides
3x-2(+2)=x+10(+2) => 3x=x+12
subtract x on both sides
3x(-x)=x(-x)+12 => 2x=12
divide 2 on both sides
2x/2=12/2
= x=6
x+4=19-2x
subtract 4 on both sides
x+4(-4)=19(-4)-2x => x=15-2x
add 2x on both sides
x(+2x)=15-2x(+2x) => 3x=15
divide 3 on both sides
3x/3=15/3
= x=5
8z-20=z+15
subtract z on both sides
8z(-z)-20=z(-z)+15 => 7z-20=15
add 20 on both sides
7z-20(+20)=15(+20)
7z=35
divide 7 on both sides
7z/7=35/7
= z=5
5x + 3y = -15 + y= 2/3x + 9
solve for x: tan(180-ø).tan(90+ø)+xcos(90+ø).(cos90-ø) =sinø.(sin180-ø)
Answer:
Below.
Step-by-step explanation:
tan(180-ø).tan(90+ø)+xcos(90+ø).(cos90-ø) = sinø(sin180-ø)
xcos(90+ø).(cos90-ø) = sinø(sin180-ø) - tan(180-ø).tan(90+ø)
x = (sinø(sin180-ø) - tan(180-ø).tan(90+ø)) / cos(90+ø).(cos90-ø)
x = - (sin^2ø + tanø(tan(90+ø)) / cos^2ø

Complete Question
Mis. Jackson wants to rent a van for a week it will cost a weekly fee plus 0.20 per mile driven let m equal the number of miles Ms. Jackson drives during the week write an algebraic expression that shows a week rent Jackson will pay for the van for the week
Answer:
A = w + 0.20m
Step-by-step explanation:
Step 1
We find the equation for the total amount spent in a week
The total amount to rent the van in a week = A
Weekly fee = w
Number of miles = m
Therefore, thw algebraic expression that shows a week rent Jackson will pay for the van for the week is
A = w + 0.20m

What is the area, in square meters, of the shaded region in the diagram?
Answer:
Notice that the side length of the square is 38 m.
area of square = (side length)2 = (38 m)2 = 1444 m2
Notice that the diameter of the circle is 38 m .
And its radius = diameter / 2 = 38m / 2 = 19 m
area of circle = pi * radius2 = pi * (19m)2 = pi * 361 m2 ≈ 1133.54 m2
So......
area of shaded region = area of square - area of circle
area of shaded region ≈ 1444 m2 - 1133.54 m2
area of shaded region ≈ 310.46 m2
Step-by-step explanation:
Notice that the side length of the square is 38 m.
area of square = (side length)2 = (38 m)2 = 1444 m2
Notice that the diameter of the circle is 38 m .
And its radius = diameter / 2 = 38m / 2 = 19 m
area of circle = pi * radius2 = pi * (19m)2 = pi * 361 m2 ≈ 1133.54 m2
So......
area of shaded region = area of square - area of circle
area of shaded region ≈ 1444 m2 - 1133.54 m2
area of shaded region ≈ 310.46 m2

Write two division equations for each multiplication equation. 15⋅25=6 15 ⋅ 2 5 = 6 6⋅43=8 6 ⋅ 4 3 = 8 16⋅78=14
Answer:
[tex](a)[/tex] [tex]\frac{30}{5} = 6[/tex] and [tex]\frac{60}{10} = 6[/tex]
[tex](b)[/tex] [tex]\frac{24}{3} = 8[/tex] and [tex]\frac{96}{12} = 8[/tex]
[tex](c)[/tex] [tex]\frac{112}{8} = 14[/tex] and [tex]\frac{28}{2} = 14[/tex]
Step-by-step explanation:
Given
[tex](a)\ 15 * \frac{2}{5} = 6[/tex]
[tex](b)\ 6 * \frac{4}{3} = 8[/tex]
[tex](c)\ 16 * \frac{7}{8} = 14[/tex]
Required
Write 2 division equations
[tex](a)\ 15 * \frac{2}{5} = 6[/tex]
Express 15 as 15/1
[tex]\frac{15}{1} * \frac{2}{5} = 6[/tex]
Multiply numerator and denominator
[tex]\frac{30}{5} = 6[/tex] --- This is (1)
Multiply the fraction by a common term (e.g. 2)
So, we have:
[tex]\frac{30*2}{5*2} = 6[/tex]
[tex]\frac{60}{10} = 6[/tex] ---- (2)
[tex](b)\ 6 * \frac{4}{3} = 8[/tex]
Express 6 as 6/1
[tex]\frac{6}{1} * \frac{4}{3} = 8[/tex]
Multiply numerator and denominator
[tex]\frac{24}{3} = 8[/tex] --- This is (1)
Multiply the fraction by a common term (e.g. 4)
So, we have:
[tex]\frac{24*4}{3*4} = 8[/tex]
[tex]\frac{96}{12} = 8[/tex] ---- (2)
[tex](c)\ 16 * \frac{7}{8} = 14[/tex]
Express 16 as 16/1
[tex]\frac{16}{1} * \frac{7}{8} = 14[/tex]
Multiply
[tex]\frac{112}{8} = 14[/tex] ---- This is (1)
Divide the fraction by a common term (e.g. 4)
[tex]\frac{112/4}{8/4} = 14[/tex]
[tex]\frac{28}{2} = 14[/tex]
