A.because -18 changes into positive and that would make it 18 + 12=30 and you divided it by -3x which should have x equal to -10
We can use ratios, in other words, if one part of the photo is changed x times, how many times does the other part change?
We can set up the proportion as :
width 1 : length 1 = width 2 : length 2
20 : 30 = 5 : x
We do inverse multiplication, or multiply the outer with outer and inner with inner (W1 * L2 and L1 * W2)
20*x = 30*5
20x = 150
Divide all by 10
2x = 15
Divide all by 2 to isolate x
x = 15/2
x = 7.5cm
The perimeter of a shape is the sum of its lengths. A parallelogram has four sides with two pairs of equal sides. In this case, those sides are 5 inches and 12 inches. So, the perimeter is 12*2+5*2=24+10=34 inches.
I think the answer is A. 3.
B. no, to big a number
C. no, to small a number
D. no, again, too big a number.
Have a nice day and hope this helps!
To easily solve for the ratios, divide the weight by the mass.
196/20 = 9.8
9.8 is your multiplier.
Divide 1078 by 9.8
1078/980 = 110
X = 110
Your question is the ratio of weight to mass, so from right to left.
Your correct answer is B.)
