Answer:

110 hamburgers were sold on Monday

Solving for a variable in an equation means that we want to make the variable the subject of the formula. The equation of C is: [tex]C = 0.04R + 0.06[/tex]

Given that:

[tex]R = 5(5C - 0.3)[/tex]

To solve for C, means that we make C the subject.

Divide both sides by 5

[tex]\frac R5 = 5C - 0.3[/tex]

[tex]0.2R = 5C - 0.3[/tex]

Add 0.3 to both sides

[tex]5C = 0.2R + 0.3[/tex]

Divide both sides by 5

[tex]C = 0.04R + 0.06[/tex]

Hence, the equation of C is:

[tex]C = 0.04R + 0.06[/tex]

Answer:

 (B)  4

Step-by-step explanation:

Consider the units column. The only sum of 3 and a single digit that will end in 1 is the sum ...

  3 + 8 = 11

This tells you A = 8, so the top number is 1983, and the middle number is B78.

Considering the first two columns, we know that 83 +78 = 161, so there must be a carry of 1 into the third column. That makes it have the sum ...

  1 + 9 + B = <something ending in 4>

We know the something cannot be 04 or 24, so must be 14. Then ...

  10 + B = 14   ⇒   B = 4

__

So, the whole sum is ...

  1983 +478 = 2461

and the letter values are ...

Answer:

B is 4.

Step-by-step explanation:

If we start by the ones place and add we know that to get a one the total must be 11. 11-3 = 8.  Therefore A = 8.

Now we move to the tens place, since we know A is 8 we can substitute it there.  Don't forget to add the one from the 11 we got. 1+8+7 = 16

Now we move to the hundreds place and we carry our one from 16 so now it's 1 + 9 + ? = 4, if we know that our total needs to be 14 in order to have the 4 there- 1 + 9 is 10 we can do 10 + 4 and that gets us 14. So B is 4.

Answer:

Other side = 60

Perimeter = 150

Step-by-step explanation:

Using Hypothenuse formula

25²+B²=65²

625+B²=4225

B²=4225-425

B²=3600 (Bring Square to the other side to become Square root)

B=√(3600)

B=60

Answer:

h = 5

Step-by-step explanation:

area = 1/2 base × hight

base = 3 +h

hight =9 + 6 = 15

60 = 1/2 × 15 × (3+h)

120/15 = 3 + h

8 = 3 + h

h = 5

Answer:

h = 5

Step-by-step explanation:

The value of h can be obtained by using area of triangle formula as well as distance formula.

[tex]A(\triangle ABC) =\frac{1}{2} \times AB\times AC \\ \\ 60 = \frac{1}{2} \times \sqrt{ {( - 3 + 3)}^{2} + (9 + 6) ^{2} } \\ \times \sqrt{ {(h + 3)}^{2} + {(9 - 9)}^{2} } \\ \\ 60 \times 2= \sqrt{ {( - 0)}^{2} + (15) ^{2} } \\ \times \sqrt{ {(h + 3)}^{2} + {(0)}^{2} } \\ \\ 120= \sqrt{ 0 + (15) ^{2} } \times \sqrt{ {(h + 3)}^{2} + 0 } \\ \\ 120= \sqrt{ (15) ^{2} } \times \sqrt{ {(h + 3)}^{2} } \\ \\ 120 = 15(h + 3) \\ \\ \frac{120}{15} = h + 3 \\ \\ 8 = h + 3 \\ \\ h = 8 - 3 \\ \\ h = 5[/tex]

[tex]x=-1,\displaystyle \frac{5}{3}[/tex]

Step-by-step explanation:

Hi there!

[tex]6x^2=4x+10[/tex]

Move 6x^2 to the other side of the equation:

[tex]0=-6x^2+4x+10[/tex]

Divide both sides by -2:

[tex]0=3x^2-2x-5[/tex]

Factor by grouping:

[tex]0=3x^2+3x-5x-5\\0=3x(x+1)-5(x+1)\\0=(3x-5)(x+1)[/tex]

Apply the zero product property:

[tex]3x-5 = 0\\3x=5\\\\x=\displaystyle \frac{5}{3}[/tex]

[tex]x+1=0\\x=-1[/tex]

Therefore, x = -1, 5/3.

I hope this helps!

Answer:

6/5 or 1 and 1/5

Step-by-step explanation:

To do this you need to multiply 6/1, 2/3, and 3/10 all together by cancelling out the numerator in 3/10 and the denominator for 2/3. Then you would be left with 6*2*1/10

This simplifies to 6*1/5 because of the 2*1/10 is 1/5, because 1/5 doubled is 1/10.

then multiply the numerator and 6 together to get 6/5.

Hope this helps!
