Answer:
D. 35/12
Step-by-step explanation:
Answer:
D
Step-by-step explanation:
Δ CED and Δ CAB are similar thus the ratios of corresponding sides are equal, that is
= 
, substitute values
= 
= 
( cross- multiply )
12x = 156 - x ( add x to both sides )
13x = 156 ( divide both sides by 13 )
x = 12
Thus
AC = 156 - x = 156 - 12 = 144 → D
Answer:It doesn't make sense when I try to do it,I even tried a calculator
Step-by-step explanation: IDK?
You have to multiply both numbers with the same factor. What I mean, 475/58 gives you 8 R 11. Now let's try this, (475x2=950) and (58x2= 116) so our new numbers are 950/116 which gives us the same answer 8 R 11 ! I hope this helped.. But let's try another one, keep in mind, you can multiply the number by any factor AS LONG AS you multiply them with the SAME factor. So if you multiply 475 by 5, then you have to multiply the 58 by 5 as well. Now let's try, (475x5=2375) and (58x5= 290) therefore, 2375/290 = which gives you 8 R 11 ! I hope I helped . I am a Palestinian student in Palestine in grade 11 and you just brought me back to grade 4 memories ! math is fun when you get it (: good luck
Answer:
y = 2
Step-by-step explanation:
I will solve this problem, using the elimination method.
-2(5x - 3y) = -11
-10x + 6y = 22
2x - 6y = -14
Subtract and divide for x
-8x = 8
x = -1
Input -1 into the equations
2(-1) - 6y = -14
-6y - 2 = -14
-6y = -12
y = 2
Thanks!
