\\ \sf\longmapsto 15(x+1)=150

\\ \sf\longmapsto x+1=\dfrac{150}{15}

\\ \sf\longmapsto x+1=10

\\ \sf\longmapsto x=10-1

\\ \sf\longmapsto x=9

Answer:

x=9

Step-by-step explanation:

15\left(x+1\right)=150

<u>⇒ Divide both sides by 150:-</u>

<u />\frac{15\left(x+1\right)}{15}=\frac{150}{15}

x+1=10

<u>⇒ Subtract 1 from both sides:-</u>

<u />x+1-1=10-1

x=9

Use logarithms to solve each equation 2x9/8=111
Illusion [34]
<span>We have this equation:
</span>
2x^{\frac{9}{8}} = 111

and we need to find the value of x.

First of all, we multiply the whole equation for 1/2, so our goal is to isolate x, therefore:

x^{\frac{9}{8}}=\frac{111}{2}
 
Next step we must do is to apply <span>logarithms:
</span>
logx^{\frac{9}{8}} = log(\frac{111}{2})

Next, we have to apply identities and then to solve the equation:

\frac{9}{8}logx = log(\frac{111}{2})
logx =  \frac{8}{9}log(\frac{111}{2})
logx = 1.5504
10^{logx} =  10^{1.5504}

Finally, we have the value of x which was our goal. This is the answer for the question above:

x= 35.5140

Find the measure or angle xyz
blagie [28]

Answer:

The answer to your question is: 85°

Step-by-step explanation:

Data

m∠ xyz = 2m∠x - 9

m∠w = 38°

Process

∠x = (∠xyz + 9) / 2

∠ y = 180 - ∠xyz

∠w + ∠y + ∠x = 180

                             

Substitution              38 + (180 - ∠xyz) +   (∠xyz + 9) / 2 = 180

                                 76 + 360 - 2∠xyz + ∠xyz + 9 = 360

Simplify

                                 85 - 2∠xyz + ∠xyz = 0

                                  85 = ∠ xyz

The variable, y, varies directly with x. If y = 26 when x = 21,<br> what is y when x = 64?
STatiana [176]

Answer:

y=69

Step-by-step explanation:

first step:when y=26 and x=21

c=y-x

c=26-21

c=5

second step: when y is unknown and x=64

To find y we simply add the value of c to x

y=x+c

y=64+5

y=69

If 32 horses consume 112 kg of grass in a certain period, how much grass will be
Aloiza [94]

Answer:

38.5 kg of grass

Step-by-step explanation:

We can solve this problem by using a proportion. (Kg of grass over horses)

Let x = the amount of grass 11 horses will eat in the same period of time.

112/32 = x/11      Cross multiply

1232 = 32x        Divide both sides by 32

x = 38.5

I hope this helped and please mark me as brainliest!
