Answer:

Step-by-step explanation:

Since the two triangles are congruent, all their angles are as well.

So you can set 4y-10 = 3y+5 since they are the same angles.

Now solve the system by putting the y's on the left side and coefficients on the right side:

y=15.

Answer:

y=5

Step-by-step explanation:

Since the two triangles are congruent to each other. Angles R and X are congruent to each other.

Set the equations to each other.

4y - 10 = 3y+5

1.) Add 10 to both sides

4y= 3y +15

2.) Subtract 3y to both sides

3y=15

3.) Divide by 3 to get y by itself

y=5

The area of a rectangle is 4w - 10 square units.
podryga [215]

Area of rectangle = 2(2w - 5) is the factored form of given expression

Multiplying the length and width of a rectangle, we get the area of the rectangle

<em><u>Solution:</u></em>

Given that, area of rectangle is 4w - 10 square units

We have to factor the expression

From given,

Area of rectangle = 4w - 10

Take 2 as common factor

Area of rectangle = 2(2w - 5)

Thus the given expression is factored

<em><u>The area of rectangle is given as:</u></em>

Area\ of\ rectangle = length \times width

Area\ of\ rectangle = 2 \times (2w - 5)

Thus, multiplying the length and width of a rectangle, we get the area of the rectangle

When we multiply 2 with 2w - 5 we get the area of rectangle

From above we can say,

Length = 2 or 2w - 5

Width = 2w - 5 or 2

So when dimensions of rectangle are multiplied we get area of rectangle

the current temperature in small town - 20 degrees Fahrenheit this is 6 degrees less than twice the temperature that was six hou
Vlad [161]
For problems like this we can use algebra to help us, the farenheight 6 hours ago was:
 (2xt)-6=-20
We have to balance the sides out, first we minus 6
2xt=-26
Now we can divide by 2
t=-13

We now know the temperature 6 hours ago was -13

At a jeans factory, a random quality check found 8 pairs defective and 292 pairs with no problems. how many defective pairs can
anygoal [31]
Hello!

to solve this equation, you have to find the percentage of defects out of the total amount of jeans. if there are 300 pairs of jeans with 8 faulty pairs, then the percentage of defects would be 2.666(etc). 2.666(etc) percent of 3000 is roughly 80 pairs of defective jeans.

therefore your final answer would be 80 pairs of jeans!
