Answer: E
Step-by-step explanation: I had this same question on a test a few mins ago
<span><span>2<span>(<span>1+<span>5x</span></span>)</span></span>=<span>5<span>(<span><span>2x</span>−1</span>)</span></span></span>
Step 1: Simplify both sides of the equation.<span><span>2<span>(<span>1+<span>5x</span></span>)</span></span>=<span>5<span>(<span><span>2x</span>−1</span>)</span></span></span><span><span><span><span>(2)</span><span>(1)</span></span>+<span><span>(2)</span><span>(<span>5x</span>)</span></span></span>=<span><span><span>(5)</span><span>(<span>2x</span>)</span></span>+<span><span>(5)</span><span>(<span>−1</span>)</span></span></span></span>(Distribute)<span><span>2+<span>10x</span></span>=<span><span><span>10x</span>+</span>−5</span></span><span><span><span>10x</span>+2</span>=<span><span>10x</span>−5</span></span>
Step 2: Subtract 10x from both sides.<span><span><span><span>10x</span>+2</span>−<span>10x</span></span>=<span><span><span>10x</span>−5</span>−<span>10x</span></span></span><span>2=<span>−5</span></span>
Step 3: Subtract 2 from both sides.<span><span>2−2</span>=<span><span>−5</span>−2</span></span><span>0=<span>−7</span></span><span>

Is x =4? if so
4^3-(3+4)^2
=64-(7)^2
=64-49
=15
Answer:
A:2
B:-5
C:8
D:-147
Step-by-step explanation:
A: For this one, you can cancel out the negatives. Then just divide 14 by 7. Your final answer is 2. Final Answer : 2
B: This one you can forget about the negative for the first bit. Just divide 15 by 3 to get 5. Now the negative is only on one side of the equation so therefore we add the negative back into our answer. Final Answer : -5
C: Just divide 32 by 4 to get 8. No removal or substitution is needed for this one because both numbers are positive. Final Answer : 8
D: Multiply both numbers normally forgetting about the negative at first. 49 * 3 is 147. Now one of our numbers contain a negative so we plug back the negative into our answer. Final Answer : -147
Answer:
22 times
Step-by-step explanation:
Since there are four colors that cycle in each pattern stage (blue green yellow orange) and there are 88 beads, there would be 22 repetitions of the pattern since 88/4 = 22.
