Answer:
We know that:
For every two flowers that Kayra sells, Mycho sells 5.
Now, in the question we have:
"If Kayra sold 6 newspapers, how many did Mycho sell?"
There is no information about newspapers, so we can't answer anything.
If we had something like:
"If Kayra sold 6 flowers, how many did Mycho sell?"
Well, in this case, we remember that for every 2 flowers that Kayra sells, Mycho sells 5, then the first thing we need to do is count how many groups of 2 flowers we have in 6 flowers, this is:
6/2 = 3 groups.
And for each one of these, Mycho will sell 5 flowers, then the total number of flowers that Mycho sold is:
3*5 = 15 flowers.

Answer:
x = - 8/23
y = 40/23
Step-by-step explanation:
-5x- y = 0
and
-8x+3y = 8
The first step to solve this would be to get what one of the two variables equal. The easiest in this case is y from the first equation.
-5x-y = 0
-y = 5x
y = - 5x
Now you can take this y value and plug it into the section equation.
-8x + 3(-5x) = 8
-8x - 15x = 8
-23x = 8
x = - (8/23)
Once you get the x value you can plug it back into equation one to get y's value
-5*-(8/23) - y = 0
40/23 - y = 0
y = 40/23

Find the value of each variable and the measure of each labeled angle (2x) (3x-42)
Step-by-step explanation:
Head opposite angles
2x= 3x-42
x= 42°
the angles are 84°
Each of the pairs of opposite angles made by two intersecting lines is called a pair of vertical angles. The value of x is 42 and the measure of the two given angles is 84° each.
What are vertical angles?Each of the pairs of opposite angles made by two intersecting lines is called a pair of vertical angles.
The two of the given angles are vertically opposite angles, therefore, the measure of the two given angles will be the same.
(2x)° = (3x - 42)°
2x = 3x - 42
Subtract 2x from both sides of the equation and add 42 to both sides of the equation,
2x - 2x + 42 = 3x - 42 - 2x + 42
42 = 3x - 2x - 42 + 42
42 = x
Therefore, the value of x is 42. Now, the measure of each angle can be written as,
(2x)° = 2(42) = 84°
(3x - 42)° = 3(42) - 42 = 84°
Hence, the value of x is 42 and the measure of the two given angles is 84° each.

y = 1/7x + 26
y = 7x + 26
x = 7y + 26
Answer:
y=7x+26
Step-by-step explanation:
First we have to find the slope of the lines.

Our slope is going to equal 7
then we take a point and use it to find the equation

The rate of interest will be 0.35.
What is compound interest?
Compound interest is the interest calculated on the principal and the interest accumulated over the previous period.
Compound interest formula[tex]CI = P(1+\frac{r}{n}) ^{nt} -P[/tex]
and, the Amount is given by
[tex]A = P(1+\frac{r}{n} )^{nt}[/tex]
Where,
A is amount
P is principal
r is rate of interest
n is number of times interest is compounded per year
t is time
According to the given question
Principal, P = $210
Amount, A = $250
Time, t = 5 years
n = 1
Therefore, the interest rate is given by
Amount = [tex]P(1+\frac{r}{n}) ^{nt}[/tex]
⇒[tex]250 = 210(1+\frac{r}{1}) ^{5}[/tex]
⇒[tex]\frac{250}{210} =(1+r)^{5}[/tex]
⇒[tex]1.19 = (1+r)^{5}[/tex]
⇒[tex]\sqrt[5]{1.19} = 1+r\\[/tex]
⇒ 1.035 = 1 + r
⇒ r = 1.035 - 1
⇒ r = 0.35
Hence, the interest rate is o.35.

The ratio of boys to girls in a group is 3:1. If there are 52 more boys than girls, work out how
many people there are in total.
Answer:
104
Step-by-step explanation:
The ratio of boys : girls = 3 : 1 = 3x : x ( x is a multiplier )
There are 52 more boys than girls , so
3x = x + 52 ( subtract x from both sides )
2x = 52 ( divide both sides by 2 )
x = 26, then
3x = 3 × 26 = 78 ← number of boys
Total number = 78 + 26 = 104

a. x is equal to the number of sweat shirts made
b. $1100 is I think the base cost it takes to produce shirts
c. x=30
d. $5845
hope I helped.
Step-by-step explanation:
a. context
b. if x=the number of sweat shirts made then 65×x means that it costs $65 to produce one shirt and in that case to make any shirts it would cost $1100 to get the process set up so that they can make the shirts.
c. if c(x)=3050 then that means that that is the total cost to make all the shirts they made at that time. We know x is the number of shirts and because of that we want to solve for x. to do that we need to isolate x, the first step would be to take 3050 and sub that into the first equation
3050=1100+65x
subtract 1100 from both sides
3050-1100=65x
1950=65x
divide both sides by 65
1950÷65=x
simplify
30=x
d. you take the equation at the top c(x)=1100+65x and sub in 73 for x.
1100+(65×73)
simplify
1100+4745=5845
