5/8 + 1 1/4 = x/10 solve for x

lara [203]

Answer:

x = 75/4

Step-by-step explanation:

5/8 + 1 1/4 = x/10

5/8 + 5/4 = x/10

15/8 = x/10

8x = 15 × 10

8x/8 = 150/8

x = 150/8

x = 75/4

Find one value of x that is a solution to the equation (x^2+3)^2=4x^2+12

Westkost [7]

Answer:

${( {x}^{2} + 3) }^{2} = {4x}^{2} + 12$

$\bf \purple{ {(x + y)}^{2} = {x}^{2} + 2xy + {y}^{2} }$

${( {x}^{2}) }^{2} + 2({x)}^{2} (3) + {(3)}^{2} = {4x}^{2} + 12$

${x}^{4} + {6x}^{2} + 9 = {4x}^{2} + 12$

${x}^{4} = {4x}^{2} - {6x}^{2} + 12 - 9$

${x}^{4} = { - 2x}^{2} + 3$

$( {x}^{2} \times {x}^{2}) = { - 2x}^{2} + 3$

$2 \times {x}^{2} = { - 2x}^{2} + 3$

$= \frac{ { - 2x}^{2} + 3 }{ {2x}^{2} }$

$= 3$

Is it possible that all solutions of a homogeneous system of ten linear equations in twelve variables are multiples of one fixed

sukhopar [10]

The answer is no, because the Rank Theorem tells us that rank A + dim Nul A = 12 . Since the rank can be at most 10, the null space has to have dimension at least two.

Which of the following correctly uses absolute value to show the distance between -70 and 13?

Svet_ta [14]

The answer is 4 i think? because since -70 is negative and you're adding 13 but you're actually subtracting so ig 4 (sorry if my reasoning doesn't make sense)
