21 years ago Alvin was 11 times older than Tomio. The sum of their present age is 54.

Answer:

5 people

Step-by-step explanation:

1. I subtract 5.10 from 45 which gave me 39.90

2. I divided 39.90 by 7 to figure out how many people he could buy for

3. I had gotten 5.7 so I had to round

4 final answer is 5

Answer:

Jamie can buy lunch for 5 people.

7p≤40

Step-by-step explanation:

Given:

Jamie has $40.

Lunch cost per person = $7

Solution:

Jamie wants to treat some friends to lunch.He has $40 and knows that lunch will cost about $7 per person, p.

So, an inequality to represent this situation is written as:

Hence, the answer is 5

Therefore, Jamie can buy lunch for 5 people.

I hope this helps       :)

Answer:

[tex]1 \frac{36}{84} [/tex]

simplified :

[tex]1 \frac{3}{7} [/tex]

Step-by-step explanation:

first, we turn them into improper fractions

[tex]3 \frac{ + 3}{ \times 4} \div 2 \frac{ + 5}{ \times 8} [/tex]

First, we multiply 3×4=12+3=15 the demoninator will remain the same.

2×8=16+5=21, denominator remains the same.

[tex] \frac{15}{4} \div \frac{21}{8} [/tex]

when it comes to division with fractions, you flip the right(direction)fraction then multiply.

[tex] \frac{15}{4} \times \frac{8}{21} [/tex]

15×8=120

4×21=84

[tex] \frac{120}{84} [/tex]

then turn in back into a mixed fraction.

[tex]1 \frac{36}{84} [/tex]

demoninator remains the same, how many times 84 goes into 120, which is once(whole number) and how many is left over (numberator)

Answer:

Step-by-step explanation:

2x+3y= 6     ========================>>>           2x +  3y = 6

x+y=4    =====   times both sides by 2  =====>>>    2x + 2y = 8

             ==== subtract these two equations ==>>  (2x - 2x) + (3y - 2y) = 6 - 8

                                                                                       0x     +      y       =   -2

        y = -2     so if  x + y = 4             plug in -2 where y was

                             x + (-2) = 4              add 2 to both sides

                                    x   =  6

(6,-2)

(-2,6)

(-3, 4)

(0, 2)

Answer:

It should be D because you start off with the X coordinate then y

Answer:  

The opposite sides of a parallelogram are congruent, then

19x - 9 = 13x + 15 ( subtract 13x from both sides )

6x - 9 = 15 ( add 9 to both sides )

6x = 24 ( divide both sides by 6 )

x = 4

---------------------------------------------

Consecutive angles are supplementary, sum to 180° , that is

10y - 37 + 4y + 7 = 180

14y - 30 = 180 ( add 30 to both sides )

14y = 210 ( divide both sides by 14 )

y = 15

Then

∠ R = 10y - 37 = 10(15) - 37 = 150 - 37 = 113°

Then

∠ P = 113° ( opposite angles are congruent )

Answer:

tanA = [tex]\frac{12}{5}[/tex]

Step-by-step explanation:

tanA = [tex]\frac{opposite}{adjacent}[/tex] = [tex]\frac{BC}{AB}[/tex] = [tex]\frac{24}{10}[/tex] = [tex]\frac{12}{5}[/tex]

Answer:

67.38

Step-by-step explanation:

Tan =opposite/adjacent

=24/10

=2.4

Tan 2.4=67.38, when used on a calculator, i.e,shift tan 2.4

Answer:

150

Step-by-step explanation:

since 4 percent would have to be multiplied by 25 to get 100 you have to multiply 6 by 25. This comes out to 150. You can even check this by doing 150 times 0.04 which is 6 so we are correct!

Answer:

a. 4 (or maybe like 3.5)

b. 6

Step-by-step explanation:

a. Going from x = 0 to x = 8, it is obvious that y goes down 4 or 4.5 units during this stretch. This gives an approximate slope of -3/8. With this in mind, it can be easily calculated that going the remaining distance from x = 8 to x = 10, the value of y will be approximately 4 or so.

b. A dot literally is right next to (6, 6).
