Answer:

D. x= 4, y = 2

Step-by-step explanation:

Since it's multiple choice, you can plug in the values

Answer:

10

Step-by-step explanation:

3(2x - 4) = 4(x + 2)

  6x - 12 = 4x + 8

 -4x          -4x

  2x - 12 = 8

       +12  +12

  2x/2 = 20/2

        x = 10

Answer:

More than sorry if im wrong

Step-by-step explanation:

You need to get x by itself to solve

So to get rid of 5/2, you need to multiply both sides by the reciprocal or 2/5...

5/2*2/5 = 1 which we don't write and 1*2/5 =  2/5

So now you'd have x =2/5

Answer:

C

Step-by-step explanation:

The function is nonlinear because the slope is not constant.

Step-by-step explanation:

Area of triangle = base × height ×½

triangle = 9×8×½=36cm²

rectangle = length×width

rectangle = 15×26=390cm²

area of irregular fig= 390+36 =426cm²

Answer:

4(x+2)-6=14

or,4x+8=14

or,4x=14-8

or,4x=6

therefore,x=3/2

Answer:

x = 10

Step-by-step explanation:

RST is an isosceles triangle.

[tex]m\angle T = m \angle R\\\\

8x\degree = (3x + 50)\degree \\\\

8x = 3x + 50\\\\

8x - 3x = 50\\\|

5x = 50\\\\

x = \frac{50}{5} \\ \\ x = 10[/tex]

Step-by-step explanation:

y = 4x + 1 and y = -2x + 4

4x + 1 = -2x + 4, 6x = 3, x = 0.5

When x = 0.5, y = 4(0.5) + 1 = 3.

The point of intersection is (0.5, 3). (B)

Step-by-step explanation:

y = 4x + 1

A.(2,9)

y = 4(2) + 1 = 9

y = 9.

y = 4x + 1

9 = 4x + 1

9 - 1 = 4x

8 = 4x => x = 8÷4 = 2

x = 2.

y = -2x + 4.

A.(2,9)

y = -2(2) + 4 = 0

y = 0.

y = - 2x + 4

0 = -2x + 4

0 - 4 = 2x

0 = 2x => x = 0 ÷ 2 = 0

x = 0.

y = 4x + 1

B.(1/2, 3)

y = 4(1/2) + 1

y = 4 ÷ 2 + 1 = 3

y = 3.

y = 4x + 1

3 = 4x + 1

3 - 1 = 4x

2 = 4x => x = 2 ÷ 4 = 1/2

x = 1/2.

y = - 2x + 4

B.(1/2, 3)

3 = - 2x + 4

3 - 4 = - 2x

- 1 = - 2x => x = 1/2

x = 1/2.

y = - 2x + 4

y = - 2(1/2) + 4

y = -2(0.5)+ 4

y = -1 + 4 = 3

y = 4x + 1

C.(1,2)

y = 4(1) + 1 = 5

y = 5.

y = 4x + 1

5 = 4x + 1

5 - 1 = 4x

4 = 4x => x = 4÷4 =1

x = 1.

y = -2x + 4

C.(1, 2)

y = - 2(1) + 4

y = - 2 + 4 = 2

y = 2.

2 = -2x + 4

2 - 4 = - 2x

- 2 = - 2x => x = 2÷2 = 1

x = 1.

y = 4x + 1

D.(1/4, 2)

y = 4(1/4) + 1

y = 4(0.25) + 1

y = 1 + 1 = 2

y = 2.

y = 4x + 1

2 = 4x + 1

2 - 1 = 4x

1 = 4x => x = 1/4

Point A is the point of intersection of the lines.

Answer:

D, 2; 5

Step-by-step explanation:

Sum the equations vertically to eliminate at least one variable.

You will obtain 8y = 40.

Divide both sides by 8. You will get y = 5.

Now we know the value or y. Substitute this value into the second equation (-6x+4y = 8). You will get -6x+(4×5) = 8. Multiply 4 and 5: -6x+20 = 8.

Solve for x by moving 20 to the other side and switching sign: -6x = 8-20.

So: -6x = -12 and therefore x = 2.

So now we know the value of x and y.

(x; y) = (2; 5)

Answer:

33.04

Step-by-step explanation:

just add lolz :P

Answer:

$33.40

Step-by-step explanation:

  1  1  1

  24.95

+   8.45

__________

    33.40

5+5 is 10 so bring a 1 to the top and put a 0 for the bottom

1+9+4 is 14 so put the 4 down and put the 1 on top.

1+4+8 is 13 so put the 3 down and put the 1 on top.

1+2 is 3 so put the 3 down

then you get 33.40

Concept: Mathematical Derivation

Answer:

0.5 hours

Step-by-step explanation:

Given that Tara has covered 0.50 miles and  rides with a speed of 10 miles/hour. Felipe has  covered bike 0.25 miles and rides with a speed of 15  miles/hour.

Tara has covered more distance while the speed of Felipe is more than the speed of Tara.

Assuming that in time t hour, Felipe reaches Tara, then Tara left behind as Felipe has faster speed.

So, after t hour, Felipe will be ahead of Tara and Tara will cover lesser miles than Felipe .

As distance = speed x time, so

So, the distance covered by Tara in [tex]t[/tex] hour = 10t miles and she already has covered 0.5 miles, so total distance covered by Tara [tex]= 0.5+10t[/tex] miles.

Similarly, the distance covered by Felipe in [tex]t[/tex] hour = 15t miles and he already has covered 0.25 miles, so the total distance covered by Tara [tex]= 0.25+15t[/tex] miles.

Therefore, at the time then Felipe reached Tara, both have covered the same distance, i.e

[tex]0.25+15t=0.5+10t \\\\\Rightarrow 15t-10t=0.5-0.25 \\\\\Rightarrow 5t=0.25 \\\\[/tex]

[tex]\Rightarrow t= 0.25/5=0.5[/tex] hour

Hence, after 0.5 hours Tara will cover lesser miles than Felipe .

0.5 hours

Step-by-step explanation:

The main beverage that would easily meet Mariana's requirements would be water as it contains no sugar. Other than these two flavored options that she can choose from would be to make home-made Ice-tea or lemonade. Therefore, she can choose the amount of sugar to add without going over her own requirements, but still having a delicious beverage to drink.

Answer:

60%

Step-by-step explanation:

Formula: Markup Percentage = Selling Price Per Unit - Cost Price Per Unit over Cost price per unit. times 100

$19.99 - 12.5

-------------------   times 100

12.5

Follow PEMDAS

7.49 / 12.5 = 0.5592 (100) = 59.92

Round to the nearest whole number. So about 60%

3.the chair is shorter than 20 in

4.carlos scored over 20 points

Answer:

Step-by-step explanation:

total metre = 10m

If one piece is 4m then 2m more then that = 4 + 2 = 6m

So total = 4 + 6 = 10m

Answer:

6 1/10

Step-by-step explanation:

You multiply the left fraction by 5 and the right by 2 so the denominators come out equally as 10 which makes your new fractions, 4 5/10 and 1 6/10 then add them together and it would be 5 11/10 and you break it down so it’s 6 with 1 left over making it 6 1/10
