Expand y(3+t)

Answer:

The scale in the ratio given considers the case that there are 9 sweets (2 + 3 + 4), however, to answer our question, we need to scale up the ratio, so that we can work out the share when we have 36 sweets

Step-by-step explanation:

Ratios are a way of displaying the proportional split of a value and they are very similar to fractions. In the example above, we see that for every 2 sweets Amy has, Beth gets 3 and, Colin will get 4. Like fractions, this proportion will stay the same regardless of the scale of the ratio. The scale in the ratio given considers the case that there are 9 sweets (2 + 3 + 4), however, to answer our question, we need to scale up the ratio, so that we can work out the share when we have 36 sweets. So, what scale factor do we need to get it from a total of 9 sweets to a sum of 36 sweets? We know that 9 multiplied by 4 gives us 36, therefore, we can use a scale factor of 4. Remember how whatever is done to the denominator of a fraction has to be done to the numerator? Ratios like to behave the same way, so now that we have scaled up the sum of the ratio, we need to scale up the individual values by 4 – (2x4) : 3x4 : 4x4. Once we work it out we get the new ratio 8:12:16. You can check if you’re right by adding up the new values and you will see that 8 + 12 + 16 = 36, which is the value that the 9 was initially scaled up to. So we now know that when sharing the 36 sweets, Amy will get 8 sweets, Beth will get 12 sweets and Colin will get 16.

Answer:

x = 44

Step-by-step explanation:

6 + 5 = 11

1/4x = 11

11 ÷ 1/4 = 44

if it does not make sense, then here is the equation.

1/4(44) - 5 = 6

Answer: 121,520 jobs

Step-by-step explanation: Total jobs would be 1,736,000, multiply 1,736,000 by .07, You should get 121,520

Answer:

Rectangle

Parallelogram

Step-by-step explanation:

The ratio 3:1:3:1 shows that lengths of opposite sides of the quadrilateral are equal.

So, the possible names for the quadrilateral are rectangle, parallelogram.

Answer: x = 6

Step-by-step explanation:

it is 6 becuase when you subtract 17-5 you will get 12 ad to get 12 you need to multiply 2x6 so x=6

Answer:

6 race cars

Step-by-step explanation:

In this scenario, there would be a total of 6 race cars on the scale. Since each racecar weighs 1/4 pound then 4 racecars would equal 1. This leaves us with 1/2 or 0.5 pounds left. This would be 2 race cars since 2/4 is equal to 0.5 pounds. Therefore, if we add these two amounts up it would be a total of 6 racecars (4+2) which would total 1 1/2 pounds.

Answer:

- [tex]\frac{5x}{7}[/tex]

Step-by-step explanation:

Given

[tex]\frac{5x-10x^2}{14x-7}[/tex] ← factor out 5x in the numerator and 7 in the denominator

= [tex]\frac{5x(1-2x)}{7(2x-1)}[/tex] ← factor out - 1 on the numerator

= [tex]\frac{-5x(2x-1)}{7(2x-1)}[/tex] ← cancel the common factor (2x - 1)

= - [tex]\frac{5x}{7}[/tex]

i don't really get what the question  is could you write it again?

Answer:

a) t ≥ 5

b) (see below)

Step-by-step explanation:

First, make note of the info you are given and what you're trying to do:

- at midnight, 5°C

- drops consistently 2°C per hour

- finding t

- t = # of hours past midnight when temp. was past -4°C

- put t on a number line

So, first, you need to find the first point at when the temperature goes past -4°C. Notice that the question is asking for past -4°C, not -4°C and past. This means we're not including -4°C.

Every hour, we're dropping by 2°C. You can draw a visual to better understand the situation. See the image below.

So we know that starting from 5 am, we are lower than -4°C.

This is 5 hours from midnight.

So t ≥ 5. This means that the number of hours past midnight when the temperature was colder than -4°C was 5 or more hours.

On the number line, draw a circle on 5 (between 4 and 6), but shade it in because it includes 5. Then, shade or highlight to the right of that circle to the end of the number line.

This shows that t is equal to or greater than 5.

Answer:

Step-by-step explanation:

So, if we are looking to save money, then it would probably be a good choice to go for the least steepest line. Assuming Money stands for the Y axis and Quantity stands for the X axis, then looking at the least steepest line means the lowest Y axis, which translates to the least amount of money.

Answer:

v=2

Step-by-step explanation:

-9v-9=-27

add nine to both sides

-9v-9+9=-27+9

simplify

-9v=-18

divide both sides by -9

-9v/-9   -18/-9

simplify y=2

hope this helps :) have a nice day !!

Answer:

v=2

Step-by-step explanation:

-9v-9=-27

add nine to both sides

-9v-9+9=-27+9

simplify

-9v=-18

divide both sides by -9

-9v/-9   -18/-9

simplify y=2
