Write the given sentence as an equation. Tim s age in 7 years will be three times what it was 19 years ago.

Answers

Answer 1

Answer: Hi,
Let's say x if the actual age of Tim.
In 7 years, he will be old of x+7
19 years ago, his age was x-19
So
x+7=3*(x-19)
==>3x-57=x+7
==>3x-x=7+57
==>2x=64
x=64/2
==>x=32

Proof:
age=32
in 7 years: 32+7=39
19 years ago 32-19=11
and 39=3*11

Lines l and m are intersected by transversal t and l || m. Select all of the angles that are congruent to 25

Answers

Answer:

A. <1

D. <4

F. <8

Step-by-step explanation:

Given that lines l and m that are crossed by transversal t, the following angles are congruent to <5:

<8 = <5 (vertical angles)

<1 = <5 (corresponding angles)

<4 = <5 (alternate interior angles)

Therefore, the angles that are congruent to <5 are labelled <8, <1, and <4.

Final answer:

The angles congruent to a given angle in a set of parallel lines intersected by a transversal are the corresponding angle, the alternate interior angle, and the alternate exterior angle on the other side of the transversal.

Explanation:

In geometry, when two lines are parallel (l || m) and intersected by a transversal (t), the angles that are formed have certain relationships. Here, if one angle measures 25 degrees, then the angles congruent (equal in measure) to this angle are: the corresponding angle on the other side of the transversal, the alternate interior angle on the other side of the transversal, and the alternate exterior angle on the other side of the transversal. This is because parallel lines cut by a transversal create corresponding angles, alternate interior angles, and alternate exterior angles that are all congruent.

The teacher separated her class of twenty -eight students into two groups. One group has 4 more than twice as many students as the other group. how many students are in each group?

Answers

The class has 28 student. One group has four more students so surat 4 from 28. 28-4=24 since one of the groups have twice as many students as the other divide 24 by 3. 24 / 3 = 8. It says 1 group has for more than twice the other group so that would mean 2/3 of 24 and 4 would be the answer 16+4=20. The first group had 8 students, the other group has 20 students.

Solve for x.
- 3x + 8y = 5
6x - 2y =10

Answers

Let us solve this system by substitution.

-3x + 8y = 5
6x - 2y = 10

According to equation 2,

6x - 2y = 10

6x = 10 + 2y

thus, x = 10 + 2y / 6

substituting the value of x in equation 1,

-3 ( 10 + 2y / 6) + 8y = 5

-30 - 6y + 8y = 5 x 6 = 30

-30 + 2y = 30

2y = 60

Thus, y = 30.

Substituting the value of y in equation 2,

6x - 2y = 10

6x - 2(30) = 10

6x - 60 = 10

6x = 70.

Thus, x = 70/6.

Thus, x = 70 / 6 ( and y = 30)

The area of a rectangular pool is (14x^2+21x) square feet. If it is 7x feet long, what is the width, in feet?

Answers

(14x^2+21x) = 7x(2x + 3)

A= L * W

but L = 7x so W = 2x + 3

answer: width is (2x +3) feet

Answer:

you get (2x+3), because 14 divided by 7 = 2 and 21 divided by 7 = 3
