A car travels 80 millimetres in 2 1/2 hours . What is it speed in kilometres per hour​

Answer:

y = -3/4x -4

Step-by-step explanation:

Parallel slope = -3/4

(-4,-1)

y - y1 = m(x - x1)

y + 1 = -3/4(x + 4)

y + 1 = -3/4x - 3

y = -3/4x -4

Answer:

6 months.

Step-by-step explanation:

To find the answer, we first need to find out how much Omari paid for the down payment. To find this, you multiply 1083*0.20 and you get $216.60. So we subtract the down payment from the total leaving us with $866.40. Now to find out how many months it would take Omari to pay, we divide 866.40/144.40 since each month she pays $144.40 a month. Once you divide 866.40/144.40, you are left with an answer of 6 months.

Let's solve this problem step-by-step:

Let's set:

  [tex]-2x + 2y = 6 -- equation 1\\7x+4y=23 -- equation 2[/tex]

(equation1) * 2

  [tex]-4x+4y=12--equation3[/tex]

(equation 2) - (equation 3)

  [tex]11x = 35\\x= \frac{11}{11}--equation4\\x=1[/tex]

Plug (equation4)'s value of 'x' into (equation1)

  [tex]-2(1} )+2y=6\\-2+2y =6 \\2y = 6+2 =8 \\y =4[/tex]

Thus x= 1 and y = 4

Let's check:

 [tex]-2(1 )+2(4)=6\\2 +4 =6\\6=6\\ \\7(1)+4(4) )=23\\7+16=23\\ 23 =23\\[/tex]

Answer: x = 1 and y= 4

Give the Full Question then I will solve it..

Answer:

Jerome got 5 quarters, 1 dime and, and 3 nickels.

Step-by-step explanation:

Let's define the variables:

N = number of nickels he got

D = number of dimes he got

Q = number of quarters he got

We know that the nickels were worth $0.15

And each nickel is whort $0.05

Then:

N*$0.05 = $0.15

N = $0.15/$0.05 = 3

N = 3

Now we also know that there is a total of 9 coins, then:

N + D + Q = 9

3 + D + Q = 9

D + Q = 9 - 3 = 6

D + Q = 6

And we also know that the total change received is $1.50, then:

D*$0.10 + Q*$0.25 + N*$0.05 = $1.50

We know that N = 3, then we can replace that and get:

D*$0.10 + Q*$0.25 + 3*$0.05 = $1.50

D*$0.10 + Q*$0.25 = $1.50 - $0.15 = $1.35

D*$0.10 + Q*$0.25 = $1.35

Then we have two equations:

D + Q = 6

D*$0.10 + Q*$0.25 = $1.35

To solve this, we can isolate one of the variables in one of the equations, i will isolate D in the first one:

D = 6 - Q

Now we can replace this in the other equation:

(6 - Q)*$0.10 + Q*$0.25 = $1.35

Now we need to solve this for Q.

$0.60 - Q*$0.10 + Q*$0.25 = $1.35

Q*$0.15 = $1.35 - $0.60 = $0.75

Q = ($0.75)/($0.15) = 5

Q = 5

Then Jerome has 5 quarters.

Now we can return to the equation:

N + Q + D = 9

We already know that:

N = 3

Q = 5

Then if we replace those in the equation, we get:

3 + 5 + D = 9

8 + D = 9

D = 9 - 8 = 1

D = 1

Answer:

answer below:)

Step-by-step explanation:

Basically, start off by simplifying each pair of numbers.

The first one: [tex]2^{2}[/tex] x 5 = 4 x 5 = 20

The second one: [tex]11^{1}[/tex]= 11

The third: [tex]8^{2}[/tex]-60 = 64 - 60 = 4

Now from least to greatest, so that would be 4, 11, 20 or in this case it would then be [tex]8^{2}[/tex]-60,  [tex]11^{1}[/tex],  [tex]2^{2}[/tex] x 5

Hope it helped, good luck!!

Step-by-step explanation:

Using the percentage concept, it is found that the percentage of female students in the spring was of:

C. 63%

The percentage of an amount a over a total amount b is given by a multiplied by 100% and divided by b, that is:

[tex]P = \frac{a}{b} \times 100\%[/tex]

During the fall semester, 58% of 323 students were female, hence:

0.58 x 323 = 187.

Then, during the spring semester, the same amount out of 298, hence:

[tex]P = \frac{187}{298} \times 100\% = 63\%[/tex]

x=27

or 19-23=4

23+4=27

The length of the other base of the trapezoid is 27 meters.

A trapezoid is a polygon with four sides, it has one pair of parallel sides.

The length of the base of a trapezoid is 19 meters.

The length of the median is 23 meters.

The median in a trapezoid is a line that is in the drawn in the mid way of the two non-adjacent sides.

The value of median is half of the bases added together.

Median = (1/2) ( Base₁ +  Base₂)

Substituting the values in the formula to obtain the value of the other base.

Let x be the length of the other base,

23 = (1/2) * ( 19 + x)

23 *2 = 19+x

46 = 19 +x

x = 27 meters

The length of the other base is 27 meters.
