Answer:

q+10 = 20

Solving for q,

q=10

Step-by-step explanation:

Sum means addition and is means equals

q+10 = 20

We can solve for q by subtracting 10 from each side

q+10-10 = 20-10

q=10

Answer:

The equation is q + 10 = 20

The solution is q = 10

Step-by-step explanation:

"sum" means an addition.

"sum of q and 10" means "q + 10".

"is" means "="

That means you have the equation

q + 10 = 20

To solve the equation, subtract 10 from both sides.

q + 10 - 10 = 20 - 10

q = 10

Answer:

The equation is q + 10 = 20

The solution is q = 10

What vaule of x makes th question true? 3x+2(x-5)=50 a. 8 b.9 c.11 d.12

Ainat [17]

Hey Tierra7l,

Lets solve your equation together step by step.

$3x+2\left(x-5\right)=50$

$\mathrm{Expand}\:2\left(x-5\right):\quad 2x-10$

$\mathrm{Distribute\:parentheses\:using}:\quad \:a\left(b+c\right)=ab+ac$

$a=2,\:b=x,\:c=-5$

$2\cdot \:x+2\left(-5\right)$

$\mathrm{Apply\:minus-plus\:rules}$

$\:\:+\left(-a\right)=-a$

$2x-2\cdot \:5$

$\mathrm{Multiply\:the\:numbers:}\:2\cdot \:5=10$

$2x-10$

$3x+2x-10=50$

$\mathrm{Add\:similar\:elements:}\:3x+2x=5x$

$5x-10=50$

$\mathrm{Add\:}10\mathrm{\:to\:both\:sides}$

$5x-10+10=50+10$

$\mathrm{Simplify}$

$5x=60$

$\mathrm{Divide\:both\:sides\:by\:}5$

$\dfrac{5x}{5}=\dfrac{60}{5}$

$\mathrm{Simplify}$

$x=12$

Hope this helps,

Type the slope-intercept equation

natulia [17]

Answer:

y= -2x +1

Step-by-step explanation:

slope- intercept form:

y= mx +c, where m us the gradient and c is the y-intercept.

Let's find the value of m first using the gradient formula.

Gradient= $\frac{y1 - y2}{x1 - x2}$

$m = \frac{ - 3 - 3}{2 - ( - 1)} \\ m = \frac{ - 6}{2 + 1} \\ m = \frac{ - 6}{3} \\ m = - 2$

y= -2x +c

To find the value of c, substitute a pair of coordinates.

When x= -1, y=3,

3= -2(-1) +c

3= 2 +c

c= 3 -2

c= 1

Thus the equation of the line is y= -2x +1.

Weather Station stayed The chance of it raining is 3/5. What percent would that be?

murzikaleks [220]

Answer:

60% chance of rain

Explanation;

A way you can get the percentage would be putting the fraction in your calculator. For example here it is 3/5, when the denominator is 5 you can say 20% for each whole number.

1/5 = 20% chance
2/5= 40% chance
3/5=60% chance
4/5= 80% chance
5/5= 100% chance
