How do you solve -60 =5(2x+10)

1 answer:

3 0

You would have to do distribution you would do 5(2x) which would give you 10 and 5(10) which gives you 50 so your equation would be -60=10x+50 then you would subtract 50 from both sides which would give you -110 your equation would be -110=10x divided 10 on both sides and your answer would be x=-11

1 Solve for the unknown variable:

Burka [1]

Answer:

Approximately 6.4

Step-by-step explanation:

We can use the pythagorean thereom here, that tells us (a^2)+(b^2)=c^2. C is the hypotenuse, the side opposite from the right angle, while a and b are the other sides. We can insert 5 and 4 as a and b, and solve for c

:(5^2)+(4^2)=c^2

:25+16=c^2

:41=c^2

:sqrt(41)=6.4=c (We square rooted both sides. 6.4 is only rounded to the nearest hundredths place.) Hope this helps!

The SI unit of work is

Tju [1.3M]

Answer:

<h3> $\boxed{ \bold{ \blue{ Joule}}}$ </h3>

Step-by-step explanation:

The SI unit of work is Joule.

Further more explanation:

▪️ $\blue{ \mathsf{ {What \: is \: Work \: ?}}}$

⇒Work done by a force acting on a body is defined as the product of force and displacement of the body in the direction of the force.

▪️ $\blue{ \bold{ \sf{What \: is \: SI \: unit \: ?}}}$

⇒The system of units which is agreed by the international convention of scientists held in France in 1960 is called SI unit.

▪️ $\blue{ \bold{ \sf{What \: do \: you \: mean \: by \: \: one \: joule \: work \: \: ?}}}$

⇒One joule is the amount of work done when one Newton force displaces a body through one metre in its own direction.

Hope I helped!

Best regards!

According to the rational root theorem, which is a factor of the polynomial

vekshin1

Supposing 2x-7 were a factor, then 7/2 would be a root. Use synth. div. to determine whether 7/2 actually is a root:

__________________________
7/2 / 6 -21 -4 24 -35
21 0 -14 35
----------------------------------------
6 0 -4 10 0

Since the remainder is zero, 7/2 is a root and 2x - 7 is a factor.

A1=2 and a8=74 what is the sum

Papessa [141]

Sum of the first 8 terms in an arithmetic sequence is 304.

Given that, $a_{1}=2$ and $a_{8}=74$ .

<h3>What is sum of arithmetic sequence?</h3>

The sum of the arithmetic sequence formula is defined as the formula to calculate the total of all the terms present in an arithmetic sequence.

The sum of the first n terms in an arithmetic sequence is (n/2)⋅(a₁+aₙ).

Now, sum of the first 8 terms in an arithmetic sequence is

$a_{8}=$ (8/2).(2+74)

=4×76

=304

Therefore, sum of the first 8 terms in an arithmetic sequence is 304.
