Solve for x. 4x−3+2x2−9=1x+3 −173 −5 133 193
AnnyKZ [126]

Answer:

-1711005

Step-by-step explanation:

using BODMAS that implies you multiplication(M),before addition(A), then substraction(S) which comes last.

use the above rule to get the variable without letter only.

so ( 2*2)+(-3)=1

then 1-9=8, this part is for the left hand side which gives us 4x-8.

then the right hañd side 3-173-5133193 not including the variable with the letter x.now we have:1x-5133023.

so now

4x-8=1x-5133023

collect like terms

4x-1x=-5133023+8

3x=-5133015

divide both side by 3

x= -1711005

A scale is 10% off on measurements. The actual mass of a bracelet is 30g. What 2 masses might the scale show?
lukranit [14]

10% of 30 is .3

30 * (10/100) = .3


So 30 + .3 = 30.3

And 30 - .3 = 29.7

Which equation represents a line that passes through (4,1/3) and has a slope of 3/4? y – 3/4= 1/3(x – 4)
pogonyaev

Answer:

y – 1/3 = 3/4 (x – 4)

Step-by-step explanation:

The equation of a line is given by  y-y_1=m(x-x_1)

Where

m is the slope, and

(x_1,y_1) is the coordinates of the point given

<em>It is giventhat the slope is 3/4, so m = 3/4. Also, the point is (4, 1/3) so this is (x_1,y_1)</em>

<em />

<em />

Plugging it into the formula, we get:

y-y_1=m(x-x_1)\\y-\frac{1}{3}=\frac{3}{4}(x-4)

Hence, 2nd option is the right answer.

Solve for x. 2x+5+6x-1=120​
svetlana [45]

Answer:

x=14.5

Step-by-step explanation:

2x+5+6x-1=120​

Combine like terms (combine all of the variables and then combine all of the constants)

8x+4=120

subtract 4 on both sides

8x=116

Divide 8

x=14.5

Hope this helps!
