Answer:
false
Step-by-step explanation:
Answer:
1. 37 degrees, 2. 39 degrees, 3. 27 degrees
Step-by-step explanation:
You look at the total angle and subtract it by the angle that is given in the question since the two angles should add up to the whole angle of both. You should look at the number that is outside the angles and subtract it by the angle number inside then you will get the missing angles. The last one it is showing a 90 degree angle which is formed so you subtract 63 from 90.
Answer:
This equation has two solutions.
1 solution is: x - 1
Solution #2 is : x - 7
Step-by-step explanation:
1. Move the constant to the left. We end up with x^2 - 8x +7 = 0
2. Rewrite the expression: x^2 - x - 7x + 7 = 0
3. Factor the expressions: x * (x-1) -7(x-1) = 0
4. Separate into possible cases : (x-1) * (x-7) = 0
5. Solve the equation(s): x-1 = 0
x-7 = 0
6. Possible solutions are as follows: x-1 OR x-7
Answer:
Step-by-step explanation: x > 5
Answer:
25 pounds.
Step-by-step explanation:
1 kg = 2.2 pounds
11.5 kg = x pounds Cross Multiply
1 * x = 11.5 * 2.2
Since you are estimating the question, you don't use a calculator. So 11.5 * 2
23 pounds. 11.5 * 0.2 = 2.3 pounds
Total = 23 + 2.3 = 25.3
So the total is more than 25 but way less than 30
You can make the question a bit more formal by noticing what I did was related to the distributive property.
11.5 ( 2 + 0.2) Remove the brackets.
11.5 * 2 + 0.2*11.5 Which gives you exactly the same thing as above.
