-6(24x + 18) = 43(5 + 5x)

-144x - 108 = 215 + 215x

-108 - 215 = 215x + 144x

-323 = 359x

x = - 323/359 ⇒ Answer B. One solution in ℝ

The answer is B

-6(24x+18)=43(5+5x)
-144x - 108 = 215 +215x
-108 = 215 + 359x
-323 = 359x
-323/359 = x

If you would like me to explain more details i will!

3. Evaluate a + b for a = -46 and b= 34. A:-12 B:80 C:-80 D:12

blsea [12.9K]

Answer:

Step-by-step explanation:

Put the values of a = -46 and b = 34 to the expression a + b:

-46 + 34 use the commutative property a + b = b + a

= 34 + (-46) = 34 - 46 = -12

Points P and Q belong to segment AB . If AB = a, AP = 2PQ = 2QB, find the distance: midpoints between AP QB

Digiron [165]

Answer: The distace between midpoints of AP and QB is $\frac{a}{8}$ .

Step-by-step explanation: Points P and Q are between points A and B and the segment AB measures a, then:

AP + PQ + QB = a

According to the question, AP = 2 PQ = 2QB, so:

PQ = $\frac{AP}{2}$

QB = $\frac{AP}{2}$

Substituing:

AP + 2*( $\frac{AP}{2}$ ) = a

2AP = a

AP = $\frac{a}{2}$

Since the distance is between midpoints of AP and QB:

2QB = AP

QB = $\frac{AP}{2}$

QB = $\frac{a}{2}*\frac{1}{2}$

QB = $\frac{a}{4}$

MIdpoint is the point that divides the segment in half, so:

Midpoint of AP:

$\frac{AP}{2} = \frac{a}{2}*\frac{1}{2}$

$\frac{AP}{2} = \frac{a}{4}$

Midpoint of QB:

$\frac{QB}{2} = \frac{a}{4}*\frac{1}{2}$

$\frac{QB}{2} = \frac{a}{8}$

The distance is:

d = $\frac{a}{4} - \frac{a}{8}$

d = $\frac{a}{8}$

110 + 3x +11 = 16x + 4 solve for x

sashaice [31]

Answer:

x = 9

Step-by-step explanation:

110 + 3x + 11 = 16x + 4

121 + 3x = 16x + 4

-3x -3x

121 = 13x + 4

-4 - 4

117 = 13x

117 ÷ 13 = x

9 = x

Check:

110 + 3(9) + 11 = 16(9) + 4

121 + 27 = 144 + 4

148 = 148
