Answer:

1. 5

2. 42

3. 3

4. 14

5. 0.3333

Step-by-step explanation:

Third Grade:

8 x 5 = 40

8 + 42 = 40

21 ÷ 7 = 3

21 - 14 = 7

---------------------------21 • x = 7

Which can be written as:

21x = 7

To solve the equation above, we need to remove the 21 on the left side to make the x alone. To do that, we divide both sides by 21.

21x/21 = 7/21

21x/21 is x and 7/21 is 0.3333 which means our equation will look like this:

x = 0.3333

Thus, the answer to "21 times what equals 7?" is 0.3333.

soldier1979 [14.2K]

Answer:

Step-by-step explanation:

A) When the first equation is multiplied by 5 and the second equation by –6 ,

the equations become,

35x + 60y=54

-30x - 60y=60

Hence we can eliminate y by adding the equation.

B) When the first equation is multiplied by -5 and the second equation by 6 ,

the equations become,

-35x - 60y=54

30x + 60y=60

Hence we can eliminate y by adding the equation.

C) When the first equation is multiplied by -5 and the second equation by 7,

the equations become,

-35x - 60y=54

35x - 70y=60

Hence we can eliminate x by adding the equation.

D) When the first equation is multiplied by 5 and the second equation by -7,

the equations become,

35x + 60y=54

-35x - 70y=60

Hence we can eliminate x by adding the equation.

E) When the first equation is multiplied by -5 and the second equation by 10,

the equations become,

-35x - 60y=54

50x - 100y=60

Hence we can not eliminate x by adding the equation.

Answer:

Step-by-step explanation:

The equation of a line in point- slope form is

y - b = m(x - a)

where m is the slope and (a, b) a point on the line

Here m = 3 and (a, b) = (2, - $\frac{1}{2}$ ) , thus

y - (- $\frac{1}{2}$ ) = 3(x - 2) , that is

y + $\frac{1}{2}$ = 3(x - 2) → C

In a class test(3+) marks are given for every correct answer and (-2) marks are given for every incorrect answer (-2) marks are

Diano4ka-milaya [45]

The number of incorrect answers made by Radhika is 8; the number of incorrect answers made by Mohini = 13

<h3>How to solve algebra word problems?</h3>

We are given;

Marks obtained for 1 right answer = +3

Marks obtained for 1 wrong answer = −2

(i) Marks scored by Radhika = 20

Marks obtained for 12 correct answers = 12 × 3 = 36

Marks obtained for incorrect answers = Total score − Marks obtained for 12 correct answers = 20 − 36 = −16

Marks obtained for 1 wrong answer = −2

Thus, number of incorrect answers = (−16) ÷(−2) = 8

Therefore, the number of incorrect answers made by Radhika = 8

(ii) Marks scored by Mohini = −5

Marks obtained for 7 correct answers = 7 × 3 = 21

Marks obtained for incorrect answers = Total score − Marks obtained for 12 correct answers = − 5 − 21 = −26

Marks obtained for 1 wrong answer = −2

Thus, number of incorrect answers = (−26) ÷ (−2) = 13

So, the number of incorrect answers made by Mohini = 13
