You can easily find this answer by thinking 1.6-1.2 and since they both have 1 whole you just minus 6-2.
Answer:
×=1
Multiply both sides of the equation by 12, the least common multiple of 4,3.
3x+4(x−1)=3
Use the distributive property to multiply 4 by x−1.
3x+4x−4=3
Combine 3x and 4x to get 7x.
7x−4=3
Add 4 to both sides.
7x=3+4
Add 3 and 4 to get 7.
7x=7
Divide both sides by 7.
x=
7
7
Divide 7 by 7 to get 1.
x=1
To solve this problem you must apply the proccedure shown below:
1. You have that the the <span>archway is modeled by the equation y=-2x^2+8x and the angle mentioned in the problem is defined by the equation x−2.23y+10.34=0.
</span>
2. Therefore, you must susbtitute y=-2x^2+8x into x−2.23y+10.34=0, as below:
x−2.23(-2x^2+8x)+10.34=0
3. When you apply the distributive property, you obtain:
x−2.23(-2x^2+8x)+10.34=0
x+4.46x^2-17.84x+10.34=0
4.46x^2-16.84x+10.34=0
4. When you solve the quadratic equation, you obtain:
x=3 units
Therefore, the answer is the option D: D. 3 units.

Answer:
The 2 numbers are 158 & 199
Step-by-step explanation:
Let 1st no. = x
2nd no. = y
x + y = 357 -----(1)
x - y = 41 ------(2)
(1)-(2)
2y = 316
y = 158
suby=158into(1)
x + 158 = 357
x = 199
