the answer is negative two over zero
Answer:
f=10
Step-by-step explanation:
I don't know a formula for this but I can see that <CRE is a 90° angle so 7f+2f=90 and if f=10 7f=70 and 2f=20 which fits
2(3x-4) = 5x+6
First, expand the bracket.
6x-8=5x+6
Next, move the variables to the same side.
x-8=6
Move the -8 to the other side, change to +
x=6+8
x=14
Charlie’s solution is incorrect. When expanding the bracket, he changed the - to a +.
<span>Find
the two numbers that has the sum of 5.036
First number has a 4 in the tenths place and 7 in the thousands
=> x.4x7
The other number has 1 in the ones place and 2 in the hundredths place
=> 1.x2x
=> x.4x7 + 1.x2x = 5.036
=> x.4x7 + 1.x2x = notice that the thousandths place is 7, add 9 to make it
16.
=> x.4x7 + 1.x26 = carry 1, then in hundredths place 2 + 1 + x, find the
number to make it 3, since it’s already 3 x = 0
=> x.407 + 1.x29, in tenths place, notice that we already have 4, add 6 to
make it 10, then carry 1 to ones place
=> x.407 + 1.629, Now, in ones place, we have 1 + 1 + x, find a number to
make it 5. Add 3
=> 3.407 + 1.629 = 5.036</span>
