Hope this helps :)

-ilovejiminssi♡

a(8x + 7) = 4x + 3.5

8ax + 7a = 4x + 3.5

equating coefficients of x : 8a = 4  so a = 1/2

also 7a = 3.5 so a = 1/2

The value of a is 1/2

Answer:

[tex]3\frac{3}{4}[/tex]

Step-by-step explanation:

We have two mixed numbers and are asked to multiply them together.

2 1/4 * 1 2/3

First we convert the mixed numbers into improper fractions to make it easier for us. So follow the MA rule.

Multiply the whole number by the denominator and add the numerator.

2 1/4 * 1 2/3

9/4 * 5/3

Now multiply across,

[tex]\frac{9*5}{4*3}[/tex]

[tex]\frac{45}{12}[/tex]

Now we need to convert this back into a mixed number.

So how many times does 45 go into 12?

3 times, and 3 are left.

[tex]3\frac{3}{4}[/tex]

Simplify given fraction into mixed fraction is 3³/₄

Give that:

[tex]2\frac{1}{4} \times 1\frac{2}{3}[/tex]

Find:

Answer:

x = 6

Step-by-step explanation:

10 - 4 = 6

The x means the number is unkown, well, we know that 6+4=10, so there you go!

Answer:

6

Step-by-step explanation:

x is a mystery number. We don't know what it is, but we know that if you add 4 to it, we get 10. To what number should we add 4 to get 10?

That's right, 6.

A more advanced explanation:

We need to isolate x, so it will be alone on one side of the equation. To do this, we must subtract 4 from the left side of the equation, so it will be x + 0, or x. But we also need to remember that equations always need to be balanced, so we need to subtract 4 from both sides, to get x + 0 = 10 - 4. Simplifying, we get that x = 6.

Answer:

9 + 4.5 = 13.5 sq units

Step-by-step explanation:

The scale factor that was used in the dilation could be 1.5 units.

Suppose a figure (pre image) is dilated (dilated image) by scale factor of k. So, if a side of the figure is of length L units, and that of its similar figure is of M units, then:

L = k × M

where 'k' will be called as scale factor.

The quantities that are squares or multiple of linear things twice grow by square of scale factor.

So area of first figure = k² × area of second figure

Similarly,

The Volume of first figure = k³ × volume of second figure.

Since the scaling is done by product of some constant, that constant is called scale factor.

Then we have:

K = 4/6

K = 2/3

K = 1.5 units.

Thus, scale factor is the ratio of the new measurement to the old measurement therefore, the scale factor that was used in the dilation could be 1.5 units.

Answer:

Step-by-step explanation:

In order to determine if James and Paco earn different amounts of money per hour, you must find how much money they make in one hour.

James:

James makes $35.40 in 3 hours. So, in 1 hour, he would make 35.40/3 = 11.8.

James makes $11.80 an hour.

Therefore, his equation would be d = 11.8h

Paco:

Paco makes $24.00 in 2 hours. So, in 1 hour, he would make 24/2 = 12.

Paco makes $12.00 an hour.

Therefore, his equation would be d = 12h

Hence, Paco and James make different amounts of money. Paco makes 20 cents, or $0.20, more than James.

Answer:

d(James) = 11.8h

d(Paco) = 12h

Paco makes $0.20/h more than James

Step-by-step explanation:

equation: y = ax + b

James:

d(Amount of money earned) = ah(number of hours worked) + b

If James worked 3 hours: 3a + b = 35.4

If James worked 5 hours: 5a + b = 59

If

3a + b = 35.4

b = 35.4 - 3a

Then

5a + b = 59

5a + 35.4 - 3a = 59

2a = 59 - 35.4

2a = 23.6

a = 23.6/2

a = 11.8

If a = 11.8, then

3a + b = 35.4

3(11.8) + b = 35.4

35.4 + b = 35.4

b = 0

If a = 11.8 and b = 0

d(Amount of money earned) = ah(number of hours worked) + b

d = 11.8h

Each hour James works, he makes $11.8

Paco:

d(Amount of money earned) = ah(number of hours worked) + b

If Paco worked 2 hours: 2a + b = 24

If Paco worked 4 hours: 4a + b = 48

If

2a + b = 24

b = 24 - 2a

Then

4a + b = 48

4a + 24 - 2a = 48

2a = 48 - 24

2a = 24

a = 24/2

a = 12

If a = 12, then

2a + b = 24

2(12) + b = 24

24 + b = 24

b = 24 - 24

b = 0

If a = 12 and b = 0

d(Amount of money earned) = ah(number of hours worked) + b

d = 12h

Each hour Paco works, he makes $12
