43 * 24 * 7 * 4 * 22 * 72 . 64 * 16 * 7 * 4 * 4 * 49 = 5619712
9x+4 =x-7 8x=-3 x=-3/8
Do you mean the following? x2 = 4 - 7x If so, then: x2 + 7x = 4 x2 + 7x + 49/4 = 4 + 49/4 (x + 7/2)2 = 65/4 x + 7/2 = ±√65 / 2 x = (-7 ± √65) / 2 So x is equal to (-7 - √65) / 2 and (-7 + √65) / 2
Answer: 7 x 8 + 4 = 60 7 x 8 = 56 56 + 4 = 60
63/7 = 9 x 4 = 36
5/7 x 4/9 = 20/63Multiply across: 5 x 4 = 20, and 7 x 9 = 63 giving the answer of 20/63
4/7 & 4/9 Bring to the same denominator of 63 ( 7 x 9) Hence we multiply the numerators by 9 & 7. (4 x 9) / 63 & (4 x 7) / 63 36/63 & 28/63 Since they are the same denominator , we now. compare the numerators 36 > 28 It follows 36/63 > 28/63 => 4/7 > 4/9
(7/9) x (4/63) = (1/9) x (4/9) = 4/81
(4/7) x (4/9) = (4 x 4) / (7 x 9) = 16/63. This fraction is in lowest terms.
7 with 4 remaining67 - 4 = 63 = 9 x 7
1 x 63, 3 x 21, 7 x 9, 9 x 7, 21 x 3, 63 x 1.
-2
When figuring out what number goes both into 56 and 63, you should look at the factor pairs. 56: 1 x 56, 2 x 28, 4 x 14, 7 x 8 63: 1 x 63, 3 x 21, 7 x 9 7 goes into both 56 and 63.
X x 9 = 63 Algebraically rearrange X = 63/9 X = 7
Sticking to integers: 7 x 9 = 63 3 x 21 = 63 1 x 63 = 63
63 = 32 x 7 I added:The factorization of 63 is 7, 3, and 3. 63 = 1 x 6363 = 3 x 2163 = 7 x 9OR3 x 3 x 7
