y=4+3x function rule

Answer:

y = 68 degrees

Step-by-step explanation:

Here, we want to solve for an equilateral triangle with the internal angle measurement being y-8

If one of the angles is y-8, then the rest are y-8 too

mathematically, by adding all , we have a total of 180

Thus;

3(y-8) = 180

y-8 = 180/3

y-8 = 60

y = 60+8

y = 68 degrees

Answer:

3 weeks

65 dollars

Step-by-step explanation:

Alright to answer this question we have to set up an equation. For greg the equation is y=13x+26 and for lucy the equation is y=10x+35. y is total amount of money saved and x is number of weeks. Since we want them to each of the same amount of money we set up the equations to be 10x+35=13x+26

then we want to get the constant and the variables alone on different sides of the equal sign so we first subtract 26 from each side to get 10x+9=13x. next we want to subtract 10x from each side and then we end up with 3x=9. Finally we divide 3 from each side to get x=3, We have answered the question to how many week it will take them to save the same amount of money but not the other part. To find out how much money they will both have in 3 weeks we plug in 3 to x. 10(3)+35 which is equal to 65. They will both have 65 dollars in three weeks

The unitary method is a method for solving a problem by the first value of a single unit and then finding the value by multiplying the single value. Unitary method a technique by which we find the value of a single unit from the value of multiple devices and the value of more than one unit from the value of a single unit. It is a method that we use for most of the calculations in math.

We are given that You can buy one can of pineapple chunks for $2

We need to Find out how many can you buy with $10

Let x be the number of cans

Using proportion;

1/2 = x/10

x = 10/2

x =5

Hence, the answer is 5 cans.

Answer:

-11, -10, -9, -8, -7, -6 and -5

Step-by-step explanation:

Given the inequality expressions

2x+9<0  and x>-12

2x+9<0

2x< 0-9

2x < -9

x < -9/2

x < -4.5

Since x >-12

-12 < x

Combining both inequalities

-12 <x  < 4.5

The integers between the intervals are -11, -10, -9, -8, -7, -6 and -5

Answer:

The answer is B. $3.85.

Step-by-step explanation:

This is because, first if we get the percentage that the shoes were marked up by, we get that they were marked up to $35, because 40% of $25 is $10 and $25 + $10 = $35.

Then, we find the percentage of $35 that she earned. In order to do this, we see what 11% of $35 is. We get $3.85, because 10% of $35 is $3.50, and 1% of $35 is $0.35. $3.50 + $0.35 = $3.85.

This is why the answer is B. $3.85.

Answer:

161 seniors

Step-by-step explanation:

According to the problem, given data are as follows:

Total number of sophomores = 300

Sophomores to junior ratio = 5:4

So, Number of Juniors = 300 ×  (4 ÷ 5)

= 240

Now, Juniors to senior ratio = 3:2

So, we can calculate the number of seniors by using following method:

Number of seniors = 240 × ( 2 ÷ 3)

= 240 × 0.67

= 160.8 or 161

Answer:

The mean temperature for the first 8 days in January is 5.375 °C

Step-by-step explanation:

The means = The sum ÷ The number

∵ The mean temperature for the first 7 days in January was 5 °C

∴ The mean = 5

∴ The number = 7

→ Substitute them in the rule above

∵ 5 = The sum ÷ 7

→ Multiply both sides by 7

∴ 35 = The sum

∴ The sum of the temperature for the first 7 days is 35 °C

∵ The temperature on the 8th day was 8 °C

→ Add it to the sum of the first 7 days to find the sum of the first 8 days

∴ The sum of the first 8 days = 35 + 8

∴ The sum of the first 8 days = 43 °C

∵ The number of days = 8

→ Substitute them in the rule above to find the mean

∴ The mean = 43 ÷ 8

∴ The mean = 5.375 °C

∴ The mean temperature for the first 8 days in January is 5.375 °C

Answer: $18.19

Step-by-step explanation:

The tax is applied after the discount so first find the discounted price:

= Price * ( 1 - discount rate)

= 20 * ( 1 - 15%)

= $17

The sales tax of 7% can then be applied:

= Price * ( 1 + tax rate)

= 17 * ( 1 + 7%)

= $18.19

Answer: hi want to be fwends

Step-by-step explanation:

There can 3 songs to be played for per quarter.

A unit conversion expresses the same property as a different unit of measurement.

Given that, It cost Sean 3.75 to play 45 songs on an old jukebox. The jukebox only accepts quarters.

Converting $3.75 into quarters,  ($1 = 4 quarters)

$3.75 = 3+0.75

= 3x4+0.75

= 12+3

= 15 quarters

So, he played 45 songs in 15 quarters

Therefore, in 1 quarters = 45/15

= 3

Hence, There can 3 songs to be played for per quarter.

Answer:

C) 4.0 ft  

Step-by-step explanation:

We will use the Pythagorean theorem to solve this.  It states that the sum of the squares of the legs of a right triangle is equal to the square of the hypotenuse; algebraically,

a²+b² = c²

The height splits the base in two, giving us a leg of 3.  The hypotenuse is 5.  This gives us:

3²+b² = 5²

9+b² = 25

Subtract 9 from each side:

9+b²-9 = 25-9

b² = 16

Take the square root of each side:

√b² = √16 = 4
