Answer:
NO, YES, YES, NO
Step-by-step explanation:
Subsitute the number they give you and then solve. Finally, see if the equation is true.
13 - 7 = 20 This is equation is not true. (NO)
15 · 8 = 120 This equation is true. (YES)
24/12 = 2 This equation is true. (YES)
5 = 10 + 5 This equation is not true. (NO)
To solve this, you will have to set up your equation as fractions:
X is to 4 as 4 is to 4+3, or 7
X/4 = 4/7
You will then cross multiply
7x = 4•4
7x = 16
Divide.
X = 2.285714...
Round to the nearest hundredth.
