The answer is 4c-10
10 + 25 (35) is less than 40 - 10 (30)
For these you just plug in the value given for the variable (in this case, c) to each choice until you find the one is true
Answer:
Step-by-step explanation: I'm assuming this problem says 56 divided by 7 times 2 in the numerator; OVER 4 to the second power in the denominator. First step would be to multiply 7 times 2, giving you 14. Thus u have 56 divided 14, which is 4. In the denominator, it says 4 to the second power, which is 16. Now u have 4 OVER 16. Now we will reduce the fraction. Both numerator and denominator have a GCF of 4. So we divide top and bottom number by 4. The end result is 1 OVER 4.
Answer:
5 meters
Step-by-step explanation:
Since, the 3m and 4m are NOT the hypotenuse (since the hypotenuse is diagonal) we can use the pythagorean thm.
W+d=869
w=d-81
plug in
(d-81)+d=869
2d-81=869
+81 both sides
2d=950
÷2 both sides
d=475
dryer cost $475
let's check w=475-81
w=394
475+394=869
869=869
the solution is true :)
Answer:
Side-Angle-Side similarity is what will tell you that ABD ≈AEC.
Step-by-step explanation:
Since ABE is isosceles, that means that AB=AE, and that angles B and E are equal. In the problem they tell you that BD is congruent to EC, so you have the three pieces of information that you need. The angle is between the two sides, so triangles ABD and AEC are congruent by Side-Angle-Side similarity.
