Solve for x 7x-3=5x+5=

Answers

The value of x in the expression 7x-3=5x+5 is 4

Given

7x-3=5x+5

Here,

The equation is linear in variable x .

7x-3=5x+5

7x - 5x - 3 = 5

2x-3=5

2x = 5 + 3

2x=8

x = 8/2

x=4

Thus the value of x is 4 .

Find the values of a, b, and c. a = 41, b = 144, 36
a = 77, b = 118, c = 62
a = 36, b = 103, c = 77
a = 36, b = 118, c = 62

Answers

Answer:

The correct option is 4.

Step-by-step explanation:

If a transversal line intersect two parallel line, then the alternate interior angles are equal.

$a^(\circ)=36^(\circ)$

The value of a is 36.

The sum of two interior angle is equal to the exterior angle of third vertex.

$77+c=139$

$c=139-77$

$c=62$

The value of c is 62.

If two angles lie on a straight line, then they are supplementary angles and their sum is 180 degree.

$b+c=180^(\circ)$

$b+62^(\circ)=180^(\circ)$

$b=180^(\circ)-62^(\circ)$

$b=118^(\circ)$

The value of b is 118.

Therefore option 4 is correct.

a = 36, b = 118, c = 62

Hi guys can u please help and doing hw and i don't understand.

Answers

Answer:

Step-by-step explanation:

The weight of the weight lighting bar = the initial value/y-intercept (b) = 45

Amount of weight = x

Total amount of weight = y

The rate of change (m) = 1

Thus to write the function that models this situation, substitute m = 1, and b = 45 into y = mx + b

Thus:

y = (1)x + 45

y = x + 45

The correct option is c

Dorothea is making friendship bracelets. She has 260cm of string. She needs 20 cm for each bracelet. How many bracelets can she make?

Answers

Answer:

13 bracelets

Step-by-step explanation:

If you have 260 cm of string and you need 20 cm for each bracelet, you have to divide 260 by 20. Which gives you 13

Answer: Dorothea can make 13 bracelets.

Step-by-step explanation: If Dorothea has 260cm of strings, she should cut the string accordingly to set aside the strings. Cutting 260cm of 20cm length each would be the same as doing 260 divided by 20. If you do the math (mentally or using a calculator), you would get 13 pieces of strings, meaning Dorothea can make 13 bracelets. Hope this helped!
