Answer:

Step-by-step explanation:

You want to find the number of dimes (x) and the number of quarters (y) in 19 coins that have a total value of $3.55.

Using the given variables, we can write two equations. One is for the number of coins; the other is for their value.

  x + y = 19 . . . . . . . . . . . number of coins

  10x +25y = 355 . . . . . value in cents

It usually works well to solve an equation involving the highest-value coin. That means we want to eliminate the x-variable. Using the first equation, we can write ...

  x = 19 -y

Substituting into the second equation, we get ...

  10(19 -y) +25y = 355

  190 +15y = 355 . . . simplify

  15y = 165 . . . . . . . subtract 190

  y = 11 . . . . . . . . . . divide by 15

  x = 19 -11 = 8

The number of dimes is 8.

The number of quarters is 11.

__

Alternate solution

The average coin value is 355/19 = 18 13/19 cents. The proportion of the highest-value coins is the ratio of the difference between this value and the lowest value, divided by the difference in values.

  proportion of quarters = (18 13/19 -10)/(25 -10) = (8 13/19)/15 = (165/19)/15

  proportion of quarters = 11/19

Multiplying this by the number of coins (19) gives the number of quarters:

  (11/19)×19 = 11 . . . . quarters

You may recognize some similarities to the above solution.

Answer:

Your answer is [tex]2x^{10}[/tex].

Step-by-step explanation:

Answer:

Yes; no

Step-by-step explanation:

a. If we divide 20 by 5, we get 4. Meaning, both 4 and 5 are divisors of 20.

b. 10 is not a multiple of 20; The multiples of 20 are 20, 40, 60, 80, 100, 120, 140, etc. Multiples only go upwards not down. Nothing plus 20 is equal to 10 therefore 10 is not a multiple of 20. 20 is a multiple of 10 though.

Answer:

d. w=13.34

Step-by-step explanation:

The value of w is 13.34 for the given equation. The correct answer is option D.

A solution to an equation is a number that can be substituted for the variable to provide a true number statement.

The equation is given as follows:

3(−5.8 + w) = 22.62

First, we distribute the 3 on the left side of the equation:

-17.4 + 3w = 22.62

Next, we isolate the variable by adding 17.4 to both sides of the equation:

-17.4 + 3w + 17.4 = 22.62 + 17.4

3w = 40.02

Finally, we solve for w by dividing both sides of the equation by 3:

w = 13.34

Therefore, the value of w is 13.34, so the answer is option D.

For the given value of angle;

∠A = 62°

The complement of ∠A is; 90 - ∠A

complement = 90 - 62

complement = 28°

Now, for supplementary angle:

For the given: ∠A = 62°

supplementary = 180 - 62

supplementary = 118°

Thus, the complement and supplement are obtained as 28° and 118°.

set x as the number of the adults in the show

500-x - number of children

(500-x)×4+7.25x=3157

2000-4x+7.25x=3157

356 adult tickets was sold out.

500-356=144

144 child tickets was sold out.

Answer:

Adult tickets sold = 356

Child tickets sold = 144

Step-by-step explanation:

Given information:

Define the variables:

Create two equations from the given information:

[tex]\textsf{Equation 1}: \quad x + y = 500[/tex]

[tex]\textsf{Equation 2}: \quad 7.25x+4y=3157[/tex]

Rewrite Equation 1 to make y the subject:

[tex]\implies y=500-x[/tex]

Substitute this into Equation 2 and solve for x:

[tex]\implies 7.25x+4(500-x)=3157[/tex]

[tex]\implies 7.25x+2000-4x=3157[/tex]

[tex]\implies 3.25x+2000=3157[/tex]

[tex]\implies 3.25x=1157[/tex]

[tex]\implies x=356[/tex]

Substitute the found value of x into the rewritten form of Equation 1 and solve for y:

[tex]\implies y=500-356[/tex]

[tex]\implies y=144[/tex]

algebraic equation solving x, we concluded that In the year 1980 the approximate number of oil barrels imported from Country B per day will be 1.89 million.

An algebraic equation with simply a constant and a first-order (linear) term, such as y=mx+b, where m is the slope and b is the y-intercept, is known as a linear equation. The variables in the previous sentence, y and x, are referred to as a "linear equation with two variables" at times.

y=0.051x+1.38

Let us put y = 1.89

1.89 = 0.051x + 1.38

⇒ x = 0.51/0.051

⇒ x = 10

After ten years, 1.89 million oil barrels per day will be roughly imported from Country B.

Around 1.89 million oil barrels per day would be imported from Country B in the year 1980.

The expression that shows how many total basket the Cavaliers made during the season is 1978+f

The total number of free throws = 1484

The number of two point field goals = f

The number of 3 point field goals = 494

Total number of basket Cavaliers made during the season = Number of free throws + Number of two point goals + Number of three point field goals

Substitute the values in the equation

Total number of basket Cavaliers made during the season= 1484 + f +494

Add them together

1484+ f +494= 1978+f

Hence, the expression that shows how many total basket the Cavaliers made during the season is 1978+f

Answer:√78= 8.9 √98= 9.9

Step-by-step explanation:

Answer:

6/7

Step-by-step explanation:

So first, we can simplify 72/98. If we divide both the numerator and denominator by 2, to get a simplified fraction.  So we need to solve 72/2 and 98/2.  72/2 = 36 and 98/2 = 49 So now we have a simplified fraction. So now, we are left with the square root of 36/49, and we apply the radical rule. So now we have simplified radicals that make things easier. The square root of 36 is 6, while the square root of 49 is 7. This is because 36 can be broken down into factors of 6 and 6, so like 6^2 = 36. So square root of 36 is 6. While 49 can be broken down as 7 and 7, so like 7^2 = 49, so square root of 49 is 7. Therefore our answer is 6/7.

Based on the enlargement the graphic designer applied to the length of the picture, the banner is as wide as 3 ⁸/₁₂ foot long

The fact that 12 inch was enlarged to 2.5 foot means that every inch is:

= 2.5/12 foot

This means that if the picture was 16 inches wide, the enlarged size of the banner would be:

= 16 x 2.5/12
