Answer:
T = 21/13
Step-by-step explanation:
Step 1: Make an expression
T is to 9 as 7 is to 39
Step 2: Cross multiply
39(T) = 7(9)
39t = 63
Step 3: Divide both sides by 39
39T / 39 = 63 / 39
T = 21 / 13
Answer: T = 21/13
The fact family using the numbers 5, 6 and 30 are 5×6=30 6×5=30, 30÷5=6 and 30÷6=5
A number system is defined as a system of writing to express numbers.
The given three numbers are 5, 6 and 30
We need to write the numbers 5 6 and 30 as
Thirty divided by five equal to six
30÷5=6
Thirty divided by six equal to five
30÷6=5
Five multiplied by six is thirty
5×6=30
Six multiplied by five is thirty.
6×5=30
Hence,the numbers 5, 6 and 30 are 5×6=30 6×5=30, 30÷5=6 and 30÷6=5

Answer:
x+7
Step-by-step explanation:
So it's been a while since I took Geometry, so I don't know what principle makes these angles equal to each other, but I know that they are in fact equal. So that means that 6x +3 = 45. Subtract 3 from each side gets you 42+6x, then divide each side by 6, which gets you your answer of x=7.
Answer:
x=8/9
Step-by-step explanation:
-3.1x+7-7.4x=1.5x+6(x-3/2)
-3.1x-7.4x+7=1.5x+6x-9
-10.5x-1.5x-6x=-9-7
-18x=-16
18x=16
x=16/18
simplify
x=8/9
