Answer:

Sum: 23 + 11 = 34

Difference: 23 - 11 = 12

Step-by-step explanation:

x + y = 34

x - y = 12

x = 12 + y

x + y = 34

12 + y + y = 34

12 + 2y = 34

2y = 22

y = 11

x + y = 34

x + 11 = 34

X = 23

A=3.14r^2 and d=12 A=?

zvonat [6]

$\huge\boxed{113.04}$

Diameter ( $d$ ) is equal to twice the radius ( $r$ ). So, find the radius by dividing $\frac{12}{2}$ . The radius, or $r$ , is $6$ .

Substitute in the value. $A=3.14*6^2$

Follow the order of operations and solve the exponent first. $A=3.14*36$

Multiply. $A=\boxed{113.04}$

Trapezoid QRST is graphed on the set of axes below.

Marta_Voda [28]

Answer:

Step-by-step explanation:

There are vertices on the x-axis, the y-axis, and the line y=x (point Q(3, 3)), so reflection on any of those lines will result in a point being invariant. The only line of reflection among the choices given that does not contain a vertex of the figure is y = -x.

reflection on y = -x will give no invariant points

Mikes truck can drive 115 miles on 5 gallons of gas. How many miles can be driven with 11 gallons of gas, using the same mpg?

LenKa [72]

Answer:

253 miles

Step-by-step explanation:

Ratio:

115:5 and x:11

Method 1:

115/5 = x/11

1265 = 5x (cross multiplying)

x = 253 miles

Method 2:

11/5 = 2.2

2.2 x 115 = 253

253 miles

Method 3:

115 / 5 = 23

23 x 11 = 253

253 miles
