Help please with this math question
Svetllana [295]
If the new technology innovation improves the production by 10%, they are increasing the amount of cars made by 10%.

Originally, 120 cars were made per day.

10% of 120 is 12.

Since the amount of cars made per day was increased by 12, we can add 12 to 120 to get 132 cars made per day (as the new unit rate).

The question asks how many cars can be produced in 5 days (after the car production increase). We can get the answer by multiplying our new daily amount of cars by 5: 132 times 5.

132 times 5 = 660

So, 660 cars can be produced in the factory in 5 days.

The system of equations can be solved using linear combination to eliminate one of the variables. 2x − y = −4→10x − 5y = −20 3x
tester [92]

Answer:

Option D is correct.

13x = 39

Step-by-step explanation:

The system of equation is given:

2x-y = -4             ....[1]

3x+5y = 59         .....[2]

Multiply equation [1] by 5 to both sides we have;

10x-5y = -20              .....[3]

Using elimination method:

Add [2] and [3] equations to eliminate y and solve for x, we have;

13x = 39

Divide both sides by 13 we get;

x = 3

Substitute x in [1] we have;

2(3)-y = -4

6-y = -4

Subtract 6 from both sides we have;

-y = -10

Divide both sides by -1 we have;

y = 10

⇒Solution: (3, 10)

Therefore, an equation can replace 3x+5y = 59 in the original system and still produce the same solution is,

13x = 39

Use the figure to find x.
velikii [3]

Answer:

Step-by-step explanation:

The sides of a 30-60-90 triangle are in the ratio 1:√3:2

The side opposite the 30° angle is (12√6)÷2 = 6/√6.

The side opposite the 60° angle is √3×6/√6 = 6/√2 =3√2.

The sides of a 45-45-90 triangle are in the ratio 1:1:√2

The hypotenuse is 3√2, so the side opposite the 45° angle is 3.

x = 3
