Explanation: the first thee are the fractions times the number in the parentheses. The last two are doing 10 divided by the fraction to get x. It's just reverse of the first three, because you have to find x in a different order, so you use division. Hope this helps.
Answer:
The value of x is 75
Step-by-step explanation:
First we need to find the other angle that doesn't have a number in it.
To find the degrees of the other angle we subtract 155 from 180.
180 - 155 = 25
Now we have to find the value of x. Add 80 and 25 together to get 105. A triangle is going to be 180 degrees. Subtract 105 from 180.
180 - 105 = 75
Now we will add 80, 25, and 75 to check our work.
80+25+75 = 180
Answer:
95.1
Step-By-Step Explanation
78:82*100 =
(78*100):82 =
7800:82 = 95.12
Now we have: 78 is what percent of 82 = 95.12
Question: 78 is what percent of 82?
Percentage solution with steps:
Step 1: We make the assumption that 82 is 100% since it is our output value.
Step 2: We next represent the value we seek with x.
Step 3: From step 1, it follows that 100%=82
Step 4: In the same vein, x%=78
Step 5: This gives us a pair of simple equations:
$100\%=82(1)
$x\%=78(2)
Step 6: By simply dividing equation 1 by equation 2 and taking note of the fact that both the LHS
(left hand side) of both equations have the same unit (%); we have
100% over x% = 82 over 78
Step 7: Taking the inverse (or reciprocal) of both sides yield
x% over 100% = 78 over 82
x = 95.12%
Therefore, 78 is 95.12% of 82

Answer:
y=2x-2
Step-by-step explanation:
first, let's put the line into y=mx+b form (slope-intercept form), where m is the slope (or gradient) and b is the y intercept
add 5 to both sides
x+2y=5
subtract x from both sides
2y=-x+5
divide by 2
y=-1/2x+5/2
perpendicular lines have slopes (gradients) that are negative (one is positive, another one is negative) and reciprocal (they are essentially the same number, just "flipped")
to find the slope of I2:
since -1/2 is negative, that means the slope of I2 will be 2 (2/1 is the reciprocal of 1/2 (positive version of -1/2))
so here's our equation so far:
y=2x+b
now we need to find b
because line will pass through (3,4), we can use it to solve for b
substitute 4 as y and 3 as x
4=2(3)+b
multiply
4=6+b
-2=b
therefore the equation is y=2x-2
hope this helps!!
