Answer:
[tex]-\left(5.3x-7y\right)\left(-9.6\right)=\:50.88x-67.2y[/tex]
Step-by-step explanation:
Given the expression
[tex]-\left(5.3x-7y\right)\times \left(-9.6\right)[/tex]
[tex]=-\left(-9.6\right)\left(5.3x-7y\right)[/tex]
Apply distributive law
[tex]a\left(b-c\right)=ab-ac[/tex]
[tex]a=-\left(-9.6\right),\:b=5.3x,\:c=7y[/tex]
so the expression becomes
[tex]=-\left(-9.6\right)\times \:5.3x-\left(-\left(-9.6\right)\right)\times \:7y[/tex]
[tex]=-\left(-9.6\right)\times \:5.3x+7\left(-9.6\right)y[/tex] ∵ [tex]-\left(-a\right)=a[/tex]
[tex]\mathrm{Remove\:parentheses}:\quad \left(-a\right)=-a,\:-\left(-a\right)=a[/tex]
[tex]=9.6\times \:5.3x-7\times \:9.6y[/tex]
[tex]=50.88x-7\times \:9.6y[/tex]
[tex]=50.88x-67.2y[/tex]
Therefore,
[tex]-\left(5.3x-7y\right)\left(-9.6\right)=\:50.88x-67.2y[/tex]
−2x+5y=−17 3x-10y=283x−10y=28
Answer:
x = 6
y = -1
Step-by-step explanation:
-2x + 5y = -17 ------ equation 1
3x- 10y = 28 ------- equation 2
equation 1× 2
-4x + 10y = -34 ------- equation 3
equation 2 + equation 3
-x = -6
x = 6
x = 6 substitute for equation 1
-12 + 5y = -17
5y = -5
y = -1

Answer:
For 1.56 to get to 1560 the decimal point moved three times.
Step-by-step explanation:
To explain this I will give a visual representation.
We have to get from 1.56 to 1,560 and find out how many times it moved forwards.
0). 1.560
1). 15.60
2). 156.0
3). 1,560
as you can see it moved three times.

Melanie rides her bike. The circumference of her bike tire is 2.8 m, and the tire revolves 1.5 times per second. What is the distance Melanie rides in 100 seconds?
Answer:
420 m
Step-by-step explanation:
The distance travelled in 1 second:
2.8 m * 1.5 revolves
= 2.8 * 1.5
= 4.2 m
Distance travelled in 100 seconds:
4.2 m * 100
= 420 m

What is the mean?
3 0 4 7 0 4 5 3 6 8
Step-by-step explanation:
3+0+4+7+0+4+5+3+6+8/10
40/10
4
Answer:
The mean is 4.
Step-by-step explanation:
When you add 3+0+4+7+0+4+5+3+6+8 you get 40 and because there are 10 numbers you would divide 40 by 10 and get 4.
Mean-the average of all of the numbers in a data set...to find the mean you simply add all of the given numbers together and then divide that sum by the total amount of numbers given, then you will get your mean.

Answer:
1. Vanilla
2.Strawberry
3.Chocolate
4.CS
5.VV
6.SS
Step-by-step explanation:
For these problem you are solving to find ALL of the possible outcomes with the 3 flavours.
1. They already have a combination for Chocolate-chocolate and Chocolate-Strawberry. The only flavour you haven't used yet is vanilla which makes your first answer vanilla.
2. They already have a combination for Vanilla-Chocolate and Vanilla-Vanilla. The only flavour you haven't used yet is Strawberry which makes your answer strawberry.
3. They already have a combination for Strawberry-Vanilla and Strawberry-Strawberry. The only flavour you haven't used yet is chocolate which makes your answer chocolate.
So when looking at the letters they are honestly just initials to the combinations possible. The order of the letters depend on what words come first going down your branch.
4. The two words are chocolate and strawberry. The first letter in both words are C and S so the answer is CS.
5. The two words are vanilla and vanilla. The first letter in both words are V and V so the answer is VV.
6. The two words are strawberry and strawberry. The first letter in both words are S and S so the answer is SS.

Answer:
x= -3/2Step-by-step explanation:
((4)²)^x = 1/(4)³
4²^x = 4³
thus the powers are same then
2x =-3
x=-3/2Answer:
x = - [tex]\frac{3}{2}[/tex]
Step-by-step explanation:
Using the rules of exponents
[tex](a^m)^{n}[/tex] = [tex]a^{mn}[/tex]
[tex]a^{-m}[/tex] ⇔ [tex]\frac{1}{a^m}[/tex]
Note that 16 = 4² and 64 = 4³ , then
[tex]16^{x}[/tex] = [tex]\frac{1}{64}[/tex] , can be expressed as
[tex](4^2)^{x}[/tex] = [tex]\frac{1}{4^3}[/tex] , that is
[tex]4^{2x}[/tex] = [tex]4^{-3}[/tex]
Since the bases on both sides are equal, then equate the exponents
2x = - 3 ( divide both sides by 2 )
x = - [tex]\frac{3}{2}[/tex]
Aaron, Darren, Karen, Maren, and Sharon rode on a small train that has five cars that seat one person each. Maren sat in the last car. Aaron sat directly behind Sharon. Darren sat in one of the cars in front of Aaron. At least one person sat between Karen and Darren. Who sat in the middle car?
Answer:
Sharon
Step-by-step explanation:
The given parameters are;
The number of persons that rode on the small train = 5
The number of cars in the train = 5
The position Maren sat = Last car
The position Aaron sat = Directly behind Sharon
The position Darren sat = In one of the cars in front of Aaron
The position of one of the members = Between Karen and Darren
The given seating arrangement is as follows;
Maren → Aaron → Sharon → Darren → Karen
Therefore, the person who sat in the middle car is Sharon.

1/8 divided by ? = 1/40
fill in the question mark
Answer:
5
Step-by-step explanation:
1/8 divided by 5 equals 1/40
Answer:
[tex]\frac{\frac{1}{8}}{5}=\frac{1}{40}[/tex]
Step-by-step explanation:
Let 'x' be the number to which 1/8 had to be divided to get 1/40
so the equation becomes
[tex]\frac{1}{8}\div \:x=\frac{1}{40}[/tex]
[tex]\frac{\frac{1}{8}}{x}=\frac{1}{40}[/tex]
[tex]\frac{1}{8x}=\frac{1}{40}[/tex]
[tex]\mathrm{Apply\:fraction\:cross\:multiply:\:if\:}\frac{a}{b}=\frac{c}{d}\mathrm{\:then\:}a\cdot \:d=b\cdot \:c[/tex]
[tex]1\cdot \:40=8x\cdot \:1[/tex]
[tex]40=8x[/tex]
switch sides
[tex]8x=40[/tex]
Divide both sides by 8
[tex]\frac{8x}{8}=\frac{40}{8}[/tex]
[tex]x=5[/tex]
x=5 is the number.
Therefore,
1/8 divided by 5 = 1/40
i.e.
[tex]\frac{\frac{1}{8}}{5}=\frac{1}{40}[/tex]
SOLUTION CHECK
[tex]\frac{\frac{1}{8}}{5}[/tex]
[tex]\mathrm{Apply\:the\:fraction\:rule}:\quad \frac{\frac{a}{b}}{c}=\frac{a}{b\cdot \:c}[/tex]
[tex]=\frac{1}{8\cdot \:5}[/tex] ∵ [tex]\frac{\frac{1}{8}}{5}=\frac{1}{8\cdot \:5}[/tex]
[tex]=\frac{1}{40}[/tex]
