HELP DUE AT 9:00 PM!

Answer:

The answer is B) a = -7/16

Step-by-step explanation:

3/4 + 4a/7 = 6a/7 + 7/8

By transposing, we get

=> 3/4 - 7/8 = 6a/7 - 4a/7

=> (by taking LCM) 6-7/8 = 6a-4a/7

=> -1/8 = 2a/7

=> -7 = 16a (by cross multiplication)

=> a = -7/16

Answer:

Hello There!

According to the question,

It is said that we have to find calories in 4 cups.

First we have to find in each cup.

So

[tex] \frac{3}{4} \times x = 99 \\ \\ so \: x = 99 \times \frac{4}{3} \\ \\ [/tex]

simplify 99 and 3 then it will look like

[tex]33 \times \frac{4}{1} [/tex]

1 has no value so 33×4=132 calories

Now it is in each cup or 1 cup.

To find in 4 cups, multiply 132×4

[tex]132 \times 4 = 528[/tex]

So 528 calories is the answer.

Answer:

The ladder meets the wall at 17.29 feet from the ground.

Step-by-step explanation:

Pythagorean Theorem ⇒ a^2 + b^2 = c^2

5^2 + b^2 = 18^2

25 + b^2 = 324

b^2 = 299

b = 17.291616

Answer:

C) a gain of 72.47 points

Step-by-step explanation:

because on 1/28 it has 13,881.93 and the next day 1/29 it has 13,954.4

subtract 13,954.4 - 13,881.93= 72.47

72.47 is the greatest amount change

And it can’t be 93.98 because in the instructions it said one day to the next not 2 day’s in advance

Answer:

The two roots are -12/5 and 18/5

Step-by-step explanation:

One way of simplifying the work involved here is to isolate y:  start this by dividing all 3 terms by 5, obtaining:

|y - 3/5| = 3

Then 3/5 is the 'center' and 3 is the distance from this center to each of the two roots.

First root is 3/5 + 3, or 3 3/5, or 18/5.

Second root is 3/5 - 3, or -2 2/5, or -12/5

Answer: I think D I might be wrong

Step-by-step explanation:

x is the days that the first team finishes the work alone (x>8)

y --------------------------second-----------------------------------------(y>8)

In a day:

⇒          [tex]\frac{1}{x}+ \frac{1}{y} =\frac{1}{8}[/tex]               (1)

If the first team works alone for two days and the second team works alone for 5 days, 5/8 of the total work still remains:

⇒          [tex]\frac{2}{x}+\frac{5}{y}=\frac{3}{8}[/tex]                (2)

(1),(2)   ⇒   [tex]\left \{ {{\frac{1}{x}+ \frac{1}{y} =\frac{1}{8}} \atop {\frac{2}{x}+\frac{5}{y}=\frac{3}{8}}} \right. <=>\left \{ {{x=16} \atop {y=24}} \right.[/tex]

It'll take the first team 16 days and the second team 24 days to finish the work alone

ok done. Thank to me :>

Answer:

Your answer is $52.2 :)

Step-by-step explanation:

First, we need to find the sale, which is 40% of $70, we can do that by doing this equation: (40% x $70) / 100 = 28.  Now we minus 28 from 70 in this equation: 70 - 28 = 42.  Now we do tax, which is 10.1% of $42.  We can do the same equation, but with the new information, so the new equation is ($42 x %10.1) / 100 which is 4.2042, and since we are talking money, we can make 4.2042, 4.2 (Rounded 0.042 down). Lastly, we add $4.2 (Tax) and $48 (Discounted price) to get $52.2. You're welcome :D
