Answer:
x =10
Step-by-step explanation:
Using the pythagoras theorem om one of the right triangle;
(√74)² = (x/2)²+7²
74 = (x/2)²+49
(x/2)² = 74 - 49
(x/2)² = 25
Square root both sides
√ (x/2)² = ±√25
x/2 = ±5
x = 2 * ±5
x = ±10
Hence the value of x is 10
Answer:
The correct one is 6 power7
Answer:
64 tomatoes
Step-by-step explanation:
If it's 8 to 2 and you multiply the ratio (x to 16) you just do to one side what you did to the other. So, if you multiplied one part of the ratio by 8, you do the same to the other. 8*8 = 64 and 2*8 = 16
(Short) Answer:
Because the absolute value of a number is the distance between the number and the origin of the line.
Step-by-step explanation:
Mrs. Shen writes the expression |-5| + |3| on the board. Show or explain why the sum |-5| + |3| is the distance between -5 and 3 on a number line.
The definition of absolute value:
For x = 0 or x > 0, | x | = x
For x < 0, | x | = - x
Because the absolute value of a number is the distance between the number and the origin of the line. (0, 0) -5's distance to the line is 5 and 3's distance to the origin of the line is 3. The sum of 5 and 3 is 8. Same with solving the absolute value, |-5| + |3| we get 5 + 3 which is 8 too.
