∆ABC is an isosceles triangle in which angles B and C are congruent.
Brut [27]
Since B and C are congruent, that means that 4x+10=x+34. Using the addition property of equality, I challenge you to solve for x! After you do that, you can note that all the angles in a triangle add up to 180, so 4x+10+x+34+angleA=180. When you find x, you can substitute that in.

If you need help with the addition property of equality for variables, here's an example - 5x+23=4x+3. Subtracting 3 from both sides, we get 5x+20=4x. Next, we can subtract 5x from both sides to get -x=20 and divide both sides by -1 to get x=-20.

Good luck, and feel free to ask with any questions!

What is the decimal multiplier to decrease by 15%?
REY [17]
<h3>Answer:   0.85</h3>

Explanation:

If we start off with $100 and decrease by 15%, then we are decreasing by $15 since 15% of 100 = 0.15*100 = 15

We start with $100 and drop to 100-15 = 85. Dividing this over the original 100 gets us 85/100 = 0.85

Put another way, 100% - 15% = 1 - 0.15 = 0.85

The decimal multiplier for "decrease by 15%" is 0.85; this sort of thing is useful if you wish to apply multiple discounts to a product.

Side note: the 0.85 can be thought of as 85%, so the product's new value is 85% of its original value

Cameron earn's $7 per hour at her after school job. The total amount of her paycheck varies directly with the amount of time she
polet [3.4K]

Answer:

Proportionality equation: y=7kx

Linear equation: y=7x

Step-by-step explanation:

So the amount that Cameron earns = 7/hr

Hours = x

And total earned amount = y

So we can form an equation from this for the total amount:

y=7x

But the question asks us for a proportionality equation so:

Proportionality constant = k

So we get the equation:

y=7*k*x
