Answer:

Equation 6x  = 12.

Step-by-step explanation:

Given  : 2x + 3y - 10 = 0  and 4x - 3y - 2 = 0 .

To find : When you eliminate y, what is the resulting equation.

Solution : We have given

2x + 3y - 10 = 0  -------(equation 1)

4x - 3y - 2 = 0 --------- (equation 2)

On adding both the equations.

2x + 3y - 10 = 0  .

4x - 3y - 2 = 0 .

_____________

6x + 0 - 12 = 0.

6x - 12 = 0 .

On adding both sides by 12

6x  = 12.

Therefore, Equation 6x  = 12.

Answer:

6x = 12

Step-by-step explanation:

2x + 3y - 10 = 0

4x - 3y - 2 = 0

add the two equations

2x + 3y - 10 = 0

4x - 3y - 2 = 0

--------------------

6x -12 = 0

add 12 to each side

6x -12 +12 = 0+12

6x =12

divide by 6

6x/6 =12/6

x =2

A metallurgist has an alloy with 5% titanium and an alloy with 30% titanium. He needs 100 grams of an alloy with 15% titanium. H
andrey2020 [161]
Let us convert the percentages to decimal format first.. so 5% is just 5/100 or 0.05 and 15% is just 15/100 or 0.15

so hmmm, so, let's say it needs "x" amount and "y" amount of each respectively, so, whatever "x" and "y" are, they must add up to 100, and whatever their concentration is, must add up to what the mixture yields

thus

\bf \begin{array}{lccclll}&#10;&amount&concentration&&#10;\begin{array}{llll}&#10;concentrated\\&#10;amount&#10;\end{array}\\&#10;&-----&-------&-------\\&#10;\textit{5\% alloy}&x&0.05&0.05x\\&#10;\textit{30\% alloy}&y&0.30&0.3y\\&#10;-----&-----&-------&-------\\&#10;mixture&100&0.15&15&#10;\end{array}&#10;\\\\\\&#10;\begin{cases}&#10;x+y=100\implies \boxed{y}=100-x\\&#10;0.05x+0.3y=15\\&#10;----------\\&#10;0.5x+0.3\left( \boxed{100-x} \right)=15&#10;\end{cases}

solve for "x"

what's "y"? well, y = 100 - x

Round off 0.043 to one significant figure
aniked [119]
Hey there :)

0.043
The first 0 before the decimal point is not significant since it is used for cosmetic purpose
The 0 after the decimal is not significant as the 0 is used to locate the decimal point
The 4 is the first nonzero integer and it counts as a significant figure

Therefore, 0.04 will be your answer rounded to 1 s.f
