Step-by-step explanation:

Answer:

for number 12 the answer is 1.5

Step-by-step explanation:

5.5 - 4 = 1.5 (answer not equation)

EQUATION : 4 + 1.5 or 5.5 - 4 either or would work ig

Answer:

Angle DAE and EAF are complementary angles, meaning that they add to 90 degrees.

Thus, we have 65+x=90

Solving for x we have 25.

Answer:

Step-by-step explanation:

2. 3/4 x 7/5 > 3/4

3. 3/4 x 5/5 = 3/4

4. 3/4 x 2/5 < 3/4

5. Multiplying a number by a fraction greater than 1 (ex: 2*1.5 = 3) results in a product greater the the number we started with. Multiplying a number by a fraction less than 1 (ex: 2*0.7 = 1.4) results in a produce smaller than the number we started with. Multiplying a number by a fraction equal to 1 (ex: 2*1 = 2) results in a product equal to the number we started with.  

Hope this helps!

Answer: b

Step-by-step explanation:

Answer: -10 × 2/5 = -4

Step-by-step explanation:

-10 × 2 = -20 -20÷5 = -4 OR

-10÷5 = -2 ×2= -4. OR

Change 2/5 to a decimal

.4 × -10 = -4

The options in answers in the question are incorrect.

Answer:

150 votes were casted

Step-by-step explanation:

So first, we know that Amy received 48 votes. Then Neil received 1/4 as many votes as Amy. So we can divide 48 by 4:

48/4=12

Neil got 12 votes. We also know that Neil and Amy's votes together is only 40% of the votes casted in total. So we can add their votes together and then find a fifth of the votes casted by dividing the 40% in half:

12+48=60

60/2=30

So now 30 votes are 20% of the total votes casted, now we just have to multiply by 5:

30*5=150

150 votes were casted

The function for the points are  y = -15x - 5

From the information given, we have that;

The points are;

(1/3,0) (-2 3/4,0) and (0,-5)

Using the point-slope form of a linear equation, we have;

y - y₁ = m(x - x₁)

Such that;

Using (1/3, 0) and (0, -5), we have that the slope is;

m = (0 - (-5))/0 -1/3)

expand the bracket

= 5 / (-1/3)

= -15

Now, take any of the given points and substitute the values

Using (1/3, 0), we get;

y - 0 = -15(x - 1/3).

y = -15x - 5.

The function for the points solved by  (1/3,0) (-2 3/4,0) and (0,-5) solved by point slope form is \(a=-15b-5\)

We have given the points:

(1/3,0) (-2 3/4,0) and (0,-5)

Using the formula of linear equation

\(a-\)\(a_{1}\)\(=x[b-b_{1}]\)                                                          

Where we will consider (1/3,0) = \(a-a_{1}\) and (0,-5) = \(b-b_{1}\)

that is 1/3 = \(a\), 0 = \(a_{1}\) and

0 = \(b\), -5 = \(b_{1}\)

\(x\) refers to the slope of line (take any variable)

Now for finding the value of \(x\),

\(x=a-a_{1}/b-b_{1}\)

inserting the values,

\(x=[0-[-5]]/[0-1/3]\\x= -15\)

Substitute the value of \(x\) in the equation

\(a-0=-15[b-1/3]\)

By simplifying the equation, we get

\(a=-15b-5\)

If we take the paycheck amount of $1020 and subtract it by the weekly salary of $300.

$1020 - $300 = $720

We get $720 in sale commissions. So to get the number of sales, you divide the $720 by the $40 per sale commission.

$720/$40 = 18

Therefore, the sales Salesman B has for the week is 18.

Answer:

y = 15

Step-by-step explanation:

We need to solve for k

y = x

21 = 7k  Divide both sides by 7 to solve for k

3 = k

y = xk

y = 5(3)

y = 15

Step-by-step explanation:

Answer:

C: 18

Step-by-step explanation:

All you have to do is write down the ratio. Then you find out that 21 is half of 42 so that means that the amount of zookeepers that you will have to add should be half the amount as well so instead of 12 it would be 6. Then you just add the two numbers together to get your final answer of 18.
