(4+3)(7-4) if you want the products to multiply each other
4+3(7-4) if you want to use the distributive property and simply have 3 multiplied but the simplification of 7-4 which is 3
The minutes taken by Grayson to text 140 words if Grayson can text 70 words in 4 minutes is 8 min.
<h3>What is division?</h3>
It is the basic arithmetic operation, in which you are separating the number into some parts.
Given:
Grayson can text 70 words in 4 minutes,
The time is taken to type one word = 4 / 70 = 0.057 min
Thus, typing 140 words Grayson would take = 0.057 × 140 = 8 min
Therefore, the minutes taken Grayson to text 140 words if Grayson can text 70 words in 4 minutes is 8 min.

A, FE as a chord is a straight line that goes from one end of the circle to another end. This means both ends of the line should touch the circumference. In FE, only one end of the line is touching the circumference. The other isn't. There FE isn't a chord for circle F
Answer: 0.25
Step-by-step explanation:
the mean is 7.25. the median is 7. so, the difference is 0.25.
Solve:
<span>-X - Y - Z =-8
- 4X +4Y +5Z=7
2X + 2Z =4 is the same as x + z = 2. Thus, z = 2 - x.
Subst. 2 - x for z in the 1st and second equations.
</span>-X - Y - Z =-8 becomes -x - y - (2 -x) = -8
- 4X +4Y +5Z=7 becomes -4x + 4y + 5(2-x) = 7
Now we have 2 equations in only 2 unknowns. Let's simplify them!
-x - y - 2 + x = -8 which becomes -y = -6, or y = 6
-4x + 4y + 10 - 5x = 7 which becomes -9x + 4y = 7 - 10 = -3
Now substitute 6 for y in this last equation: -9x + 4(6) = -3, or
-9x + 24 = -3, or
-9x = - 27 => x = 3
Then x = 3, y = 6 and z = 2 - x, or z = 2-3, or z = -1.
The solution is (3, 6, -1). Check it!!
