Answer:

4

Step-by-step explanation:

1) Hello, remember how multiplication is just addition but simplified

for example

2+2+2=6

2+2+2=6 can also be written as:

2*3(since their are 3, 2's)

2*3 and 2+2+2 give the same answer

the same case applies to te expression -6+-6+-6

since -6 is being multiplied 3 times we can write this as:

3*-6

Hope this helps!

In the figure given, what is the value of x?
torisob [31]

Answer:

x = 30

Step-by-step explanation:

In the figure attached,

Two lines are parallel and one line having two adjacent angles (4x)° and (x + 30)° are the transverse.

Sum of interior consecutive angles = 180°

So the sum of these angles = 180°

(4x)° + (x + 30)° = 180°

(4x + x) + 30 = 180

5x + 30 = 180

5x = 180 - 30

5x = 150

x = 30

Therefore, value of x = 30

Searches related to Searches related to A motorboat travels 135 kilometers in 3 hours going upstream. It travels 183 kilometers
svetlana [45]

Answer:

\large \boxed{\sf \text{The rate of the boat is } 53 \ km/h \text{, the rate of the current is }8\ km/h \ \ }

Step-by-step explanation:

Hello, let's note v the rate of the boat and r the rate of the current. We can write the following

\dfrac{135}{v-r}=3=\dfrac{183}{v+r}

It means that

135(v+r)=183(v-r)\\\\135 v + 135r=183v-183r\\\\\text{ *** We regroup the terms in v on the right and the ones in r to the left***}\\\\(135+183)r=(183-135)v\\\\318r=48v\\\\\text{ *** We divide by 48 both sides ***}\\\\\boxed{v = \dfrac{318}{48} \cdot r= \dfrac{159}{24} \cdot r}

But we can as well use the second equation:

3(v+r)=183\\\\v+r=\dfrac{183}{3}=61\\\\\dfrac{159}{24}r+r=61\\\\\dfrac{159+24}{24}r=61\\\\\boxed{r = \dfrac{61*24}{183}=8}

and then

\boxed{v=\dfrac{159*8}{24}=53}

Hope this helps.

Do not hesitate if you need further explanation.

Thank you
