Answer:

x = 17

Step-by-step explanation:

4x + 5 +107 = 180

4x + 112 = 180

      -112   -112

4x = 68

/4     /4

x = 17

We can check this work by inserting x:

4(17) + 5

73 + 107 = 180!

The actual area in square meters, of this field should be considered as the 70 m^2.

Since we know that

Area of the triangle = 1/2 * base * height.

here,

Base = 7, height = 5

And, Each square = 2 meters

So the area should be

= 1/2 * 14 * 10

= 70m

hence, The actual area in square meters, of this field should be considered as the 70 m^2.

Answer:

A. 0.125

Step-by-step explanation:

So since there is 6 numbers on a standered cube with 3 of those being odd numbers you have the fraction 3/6 but since you roll the cube three times you have 3/6 × 3/6 × 3/6. 3×3×3 is 27 and 6×6×6 is 216 you end up with 27/216. Lastly to make it a fraction you put 27 ÷ 216 in a calculator and get 0.125

Answer:

C.

Step-by-step explanation:

The reason why it is c is because:

1. First pick a point, I choose point A

2. Then it said translation 3 units right. I looked at at all the images that moved to the right by 3 units and the only ones were A and C.

3. Then it said 3 units up. Both of them moved 3 units up, so I looked at both shapes and realized that the shape in A wasn't the same as the original picture. This left me with C as my choice.

Answer:

y = 6

Step-by-step explanation:

4y - 46 + y = 4 - 5y + 10

simplify

5y - 46 = 14 - 5y

add 5 y to each side

10y - 46 = 14

add 46 to each side

10y = 60

divide both sides by 10

y = 6

Answer:

c>−1.95

Step-by-step explanation:

Step 1: Simplify both sides of the inequality.

20>−3.2c+13.76

Step 2: Flip the equation.

−3.2c+13.76<20

Step 3: Subtract 13.76 from both sides.

−3.2c+13.76−13.76<20−13.76

−3.2c<6.24

Step 4: Divide both sides by -3.2.

−3.2c−3.2<6.24−3.2
