Answer:

See below

Step-by-step explanation:

Distributive property of equality, here we are performing opposite operation, which is factoring:

60 + 12x =
6*10 + 6*2x = Show both terms as a factor of 6
6(10 + 2x) Factor out 6

(2x+1)/2=(x+2)/5 if possible can you show me step by step how to get the answer

Answer:

$\boxed{\bold{Decimal \ Form: \ x \ = \ -0.125}}$

$\boxed{\bold{Fraction \ Form:x=-\frac{1}{8}}}$

Step By Step Explanation:

Apply Fraction Cross Multiply: If $\bold{\frac{a}{b}=\frac{c}{d}:then\ a\cdot \:d=b\cdot \:c}$

$\bold{\left(2x+1\right)\cdot \:5=2\left(x+2\right)}$

$\bold{\left(2x+1\right)\cdot \:5: \ 10x+5}$

$\bold{2\left(x+2\right): \ 2x+4}$

$\bold{10x+5=2x+4}$

Subtract 4 From Both Sides

$\bold{10x+5-5=2x+4-5}$

Simplify

$\bold{10x=2x-1}$

Subtract 2x From Both Sides

$\bold{10x-2x=2x-1-2x}$

Simplify

$\bold{8x=-1}$

Divide Both Sides By 8

$\bold{\frac{8x}{8}=\frac{-1}{8}}$

Simplify

$\bold{x=-\frac{1}{8}}$

Turn Fraction Into Decimal

$\bold{-1 \ \div \ 8 \ = \ -0.125}$

$\bold{-0.125}$

100 POINTS!!!

Temka [501]

Up is the y value and left is the x value.

In the point ( t,u) t is the x value and u is the y value.

Moving to the left, you subtract the value and moving up you add the value.

The answer would be (t, u) → (-t – 3, u + 8)

Answer:

H0 : μ = 12.50

H1 : μ > 12.50

T - test

Step-by-step explanation:

Given that:

Average, μ = 12.50

Null hypothesis, H0 ;

H0 : μ = 12.50

Alternative hypothesis, H1:

Haveing a greater score on emotion recognition scale;

H1 : μ > 12.50

This is a right tailed test because the equality sign in the alternative hypothesis statement is greater than (Hence to the right).

The hypothesis will be evaluated using a t-test; when sample size is small, usually lesser Than 30

Sample size, n = 25

n < 30 (use t - test)
