.4x=.5x-30 solve for x

Mathematics
1 answer:
Nookie1986 [14]4 years ago
5 0

Answer:

x=300

Step-by-step explanation:

Multiply both sides by 10

0.4x·10=0.5x·10-30·10

Refine

4x=5x-300

Subtract 5x from both sides

4x-5x=5x-300-5x

Simplify

-x=-300

Divided both sides by -1

-x/-1=--300/-1

Simplify this and you will get x=300

Hope this Helps

HELPPPPP !!! Plzzz <br> Unit 10: circles <br> Homework 2: central angles &amp; arc measures
Zanzabum

Answer:

JL= 127       JML= 233

Step-by-step explanation:

a circle = 360 degrees and you can tell that JML is going to be larger than JL

and because of that 127 the arc with it = the same

then you do 360-127 and you get 233 for JML

What is f(x) = –4x2 + 24x + 13 written in vertex form? f(x) = –4(x – 6)2 + 23 f(x) = –4(x – 6)2 + 7 f(x) = –4(x – 3)2 + 4 f(x) =
nika2105 [10]
We have that
f(x) = –4x²<span> + 24x + 13
</span>
we know that

The vertex form for a parabola that opens up or down is:

f(x) = a(x - h)^2 + k

in the given equation, <span>a=-4</span><span>, therefore we add zero to the original equation in the form of </span><span>4h</span>²<span>−4h</span>²
f(x) = –4x² + 24x + 4h²−4h² +13
<span>Factor 4 out of the first 3 terms and group them 
</span>f(x) = –4*(x² -6x +h²) +4h² +13
<span>We can find the value of h by setting the middle term equal to -2hx
</span>−2hx=−6x
<span>h=3</span><span> and  </span><span>4h</span>²<span>=<span>36
</span></span>f(x) = –4*(x² -6x +9) +36 +13

we know that the term (x² -6x +9) is equals to------> (x-3)²
so
f(x) = –4*(x-3)² +49

the answer is
f(x) = –4*(x-3)² +49

Type the correct answer in each box. If necessary,use/for the fraction bar

0.666... is equal to 2/3 and 0.75 is equal to 3/4. 2/3 x 3/4= 6/12 which simplifies to 1/2 or 0.5.
To divide, multiply the first number by the reciprocal of the second, so 2/3 x 4/3 = 8/9.

Can someone teach me how to do this? Please and thank you
MrRa [10]

Answer:

For the first one, put the input(0) in the place of x. This would make it look like this, 3x0+5

The x is a times sign, which was added when you add the number.

The rest goes like this,

3x0=0

0+5=5

Ouput= 5
