X the 1st table
y the second
z the third
The equation is : x+y+z =16.9
But we know (given) that x=2y & z=(1/3)y
Calculate everything in term of x:
x= 2y==> x/2 =y
z=(1/3)y ==> & since y=x/2 then z= (1/3)(x/2)==> z=x/6; y=5.07 & z =1.69
x + x/2 + x/6 = 16.9===>1.666x = 16.9===> x= 10.14
Let x and y be the 2 numbers
x + y = 10
x*y = 24

Answer:
x = 6/7 of a puzzle
Step-by-step explanation:
Number of puzzle : time taken
= 3/4 : 7/8
How much a puzzle can she complete in an hour?
Let
x = number of puzzle to complete
Number of puzzle : time taken
= x : 1
Equate both ratios to solve for x
3/4 : 7/8 = x : 1
3/4 ÷ 7/8 = x / 1
3/4 × 8/7 = x / 1
24/28 = x / 1
Cross product
24 * 1 = 28 * x
24 = 28x
x = 24/28
= 6/7
x = 6/7 of a puzzle
Answer:
97°. (54°+ 43°= 97°)
Step-by-step explanation:
As we can see, the whole angle is split into two parts, one 54°, and one 43°.
To find the measure of angle a, we add 54° and 43° to get 97° .
54°+ 43°= 97°
Hope it helps!
